We're 62 days until the 2018 midterm elections and 790 days until the 2020 elections.

 

Voters are hungry for change--and they made that clear in the latest Tuesday Democratic primary that saw a longtime incumbent knocked off.

Democrat Ayanna Pressley unseated longtime Rep. Mike Capuano (D-Mass.) in his diverse Boston-area district. Capuano conceded the primary long before the AP called it, saying that "clearly the district wanted a lot of change."

Pressley's victory is the latest in a series of wins by female and minority candidates looking to change the makeup of the Democratic caucus in Congress.

Pressley, who was the first woman of color elected to Boston City Council, is poised to make history again in November as the first black woman elected to Congress from Massachusetts.

During her victory speech Tuesday night, Pressley declared that "change can't wait."

There's an anti-establishment fervor sweeping the political world this cycle. Incumbents are rarely unseated in Massachusetts and Boston politics because of an unspoken wait-your-turn mentality.

Capuano, who's served in Congress for nearly two decades, is the fourth House incumbent to lose in a primary this year.

 

Looking ahead to a primary on Thursday night, progressives are hoping that same energy hits Delaware, where they are hoping to take out the first Senate incumbent of the cycle.

Kerri Evelyn Harris, an openly gay and black Air Force veteran and community activist, is angling to unseat Sen. Tom CarperThomas (Tom) Richard CarperDem senators launch Environmental Justice Caucus Only four Dem senators have endorsed 2020 candidates Koch network launches ad campaign opposing Trump's proposed gas tax MORE (D-Del.) in the Democratic primary.

Carper is a moderate lawmaker, who's an entrenched incumbent and longtime politician. He's been in the Senate since 2001 and is a former governor and House member.

Harris and progressives are pushing him on what they say is a too friendly embrace of corportions, including pharmaceutical companies.

But Carper's campaign has sought to show his support for more progressive ideals including by backing a $15 minimum wage.

There's been no public polling and Carper has a significant fundraising advantage, but progressives are hoping to yet again overcome the odds like they did in Boston and in New York City with Alexandria Ocasio-Cortez's primary victory over longtime Democratic Rep. Joe CrowleyJoseph (Joe) CrowleyOcasio-Cortez responds to Trump calling her a 'young bartender': The 'last guy who underestimated me lost' Progressives hammer DCCC over blacklist targeting primary challenges Beto could give Biden and Bernie a run for their money MORE (D).

It's unusual for potential candidates to so aggressively position themselves for a presidential run ahead of the midterm elections. But it's a strategy that some consultants say could pay off.

Senate showdown

John McCainJohn Sidney McCainIf you don't think illegal immigrants are voting for president, think again 10 factors making Russia election interference the most enduring scandal of the Obama era Earth Day founder's daughter: Most Republican leaders believe in climate change in private MORE (R-Ariz.). Kyl, a former senator, was appointed by Arizona Gov. Doug Ducey (R) on Tuesday. Kyl said he'll serve at least through January, but hasn't committed to serving in 2019 or 2020--when McCain's seat will be up. Kyl said he isn't interested in running in 2020.

 

The Hill's Lisa Hagen traveled to Tennessee last week to cover the state's high-profile Senate race between Rep. Marsha BlackburnMarsha BlackburnConservative groups defend tech from GOP crackdown Lawmakers weigh challenges in fighting robocalls Senators show deep skepticism on Space Force proposal MORE (R-Tenn.) and former Gov. Phil Bredesen (D). Republicans have an edge in a state that Trump won by 26 points, but Tennessee Republicans told The Hill that they've seen internal numbers with both candidates ahead.

Blackburn is casting herself as a close ally of the president and also leaning heavily on her fight in the state legislature to prevent a state income tax. The conservative congresswoman would be the first woman elected to the Senate--or any statewide office--in Tennessee.

Meanwhile, Bredesen is running to the center on a bipartisan message--a move to assure Republicans they can vote for a Democrat. While he wouldn't say if he'd support Sen. Chuck SchumerCharles (Chuck) Ellis SchumerMJ Hegar announces Texas Senate bid Hillicon Valley: House Dems subpoena full Mueller report | DOJ pushes back at 'premature' subpoena | Dems reject offer to view report with fewer redactions | Trump camp runs Facebook ads about Mueller report | Uber gets B for self-driving cars Dem legal analyst says media 'overplayed' hand in Mueller coverage MORE (D-N.Y.) for leader, Bredesen called the national Democratic Party brand "terrible" as it moves more to the left. Read more here about where Bredesen needs to win to pull off an upset in Tennessee.

 

Meanwhile, Republican Senate candidates are using the 2017 tax law as a cudgel against vulnerable Senate Democrats who didn't support the GOP plan. That includes GOP candidates hitting Democratic incumbents in states like North Dakota, West Virginia and Indiana--all Senate races where Trump overwhelmingly won in 2016.

 

Survey says…

The latest generic ballot polls paint a promising picture for Democrats in the battle for the House. A Washington Post/ABC News poll released Tuesday finds Democrats retaking a wide, 14-point lead over Republicans, 52 to 38 percent. Another Tuesday poll from USA Today/Suffolk University poll also finds Democrats holding a double-digit lead, 50 to 39 percent.

What we're watching for

Thursday is Delaware's primary where Sen. Tom Carper (D-Del.) is looking to fend off his first serious primary challenge since he took office in 2001.

 

Here's the primary calendar for the rest of September: New Hampshire on Sept. 11, Rhode Island on Sept. 12 and New York's local and statewide elections on Sept. 13.

Jacky RosenJacklyn (Jacky) Sheryl RosenHillicon Valley — Presented by CTIA and America's wireless industry — Prosecutors used FISA warrant to get info on Huawei | Study finds discrimination in Facebook ads | Bezos retains voting control over ex-wife's Amazon stocks More than 30 Senate Dems ask Trump to reconsider Central American aid cuts Dem senators introduce bill to combat sexual harassment in STEM MORE (D-Nev.), launched an ad last month hitting him on his health-care record. "Jacky Rosen's idea of fixing health care? A campaign commercial," Heller says in an ad spot out Tuesday. "The truth is, in her two years in Congress, Jacky Rosen has done nothing to fix health care. Nothing. Zero."

 

The National Republican Senatorial Committee is out with a new ad attacking Democratic Senate hopeful Kyrsten Sinema as "too extreme" for Arizona. The spot goes after Sinema for "defending murderers" as a lawyer, as well as for being a "left-wing fringe protester."

 

West Virginia Attorney General and Senate hopeful Patrick Morrissey is launching the first ad of his general election campaign. The 30-second spot touts the GOP contender as a fighter, who "beat Obama at the Supreme Court" in a case that sought to block new rules on carbon emissions. The ad also channels Trump--a heavyweight move in the deep-red state. "He's going to fight for you like nobody's ever fought for the people of West Virginia," Trumps says in the clip.

 

In Florida, Democrat Andrew Gillum is out with his first TV ad since his remarkable upset win in the Democratic gubernatorial primary last month. The spot highlights the longshot nature of Gillum's campaign against a field of wealthy opponents. "The American way still lives and if the state of Florida has to show the rest of the world, then let it begin right here," Gillum says in the ad.

 

Wave watch

Democrats appear increasingly poised for a wave election in November. The Hill's Reid Wilson reports that Democrats have led Republicans by at least 11 points on five of the six most recent generic ballot polls, and many of the party's candidates have a fundraising advantage over their GOP opponents. But Republicans aren't giving up hope yet. Matt Gorman, a National Republican Congressional Committee spokesman, said that the committee was ready to "run every day as if we're down 10 points."

 

While the Democrats appear poised for a so-called "blue wave" in the House, control of the Senate remains a more elusive target for the party. Democrats are defending more than two-dozen seats this year, and Republicans are bullish about their chances of increasing their majority in the chamber.

 

Meanwhile, the NRCC says Republicans are "well-positioned" to keep control of the House in November. "In spite of history and conventional wisdom inside the Beltway, as it stands today, Republicans are well-positioned to maintain control of the House," the memo reads. The committee cites fundraising and advertising as reasons why the NRCC will defy history. The party in the White House typically loses seat in the president's first midterm election.
