Arizona Gov. Jan Brewer (R) was the only potential GOP challenger that President Obama solidly beat in the survey.

Senate Majority Leader Harry Reid (Nev.) spent more than he took in over the last three months. He burned through roughly $1.7 million since the June 8 primary, much of it going into an early broadside of advertising against Republican challenger Sharron Angle.

At the same time, Reid raised $2.4 million for his reelection effort, his campaign said Thursday. Angle, meanwhile, raised $2.29 million -- the bulk of it coming from through the "web and social media," her campaign said. It's an impressive figure considering she had some $130,000 in the bank as of May 19, according to her pre-primary filing.

"I am absolutely overwhelmed that in an economy where people are hurting, they are supporting our campaign with their money and their time. That's how much people want to retire Harry Reid," she said in a statement.

Angle's campaign spent $656,773 and now has $1,767,671 cash on hand.

Reid's campaign has spent close to $3 million since March 31, mainly on TV ads, including a new spot that went up Thursday. It's one of eight post-primary ads, which represent a flurry of spending that dropped his cash on hand from $9.42 million to $8.94 million.

The senator has raised $19.2 million for his re-election campaign to date. But with less than four months to go before Election Day, he'll need to improve his fundraising to reach his stated goal of collecting $25 million for the race. He's recently gotten some help from President Obama who was in Nevada last week for a fundraiser.

The Democratic Governors Association was so concerned about Iowa Gov. Chet Culver’s (D) prospects in a contest against Terry Branstad (R) that it tried to scuttle his gubernatorial campaign in the primary.

The DGA funneled millions to Iowans for Responsible Government, which attacked the former governor from the right during the GOP primary, according to the Des Moines Register.

One of the group’s mailings referred to Branstad as a “liberal’s liberal.” Meanwhile, in a recent e-mail to reporters, the DGA said Branstad ran “far to the right” in the June 8 primary and “has yet to demonstrate he’s running a general election campaign.”

A spokeswoman for the DGA did not respond to a request for comment.

According to the paper, the group received all of its funding — $782,500 — for a series of ads likening the Branstad to Democrats Bill Clinton and Nancy Pelosi. The group spent $767,236 in May and June, including almost $370,000 on TV advertising.

In total, the DGA has invested some $2 million in the race, including a $750,000 donation to Culver’s campaign that accounted for more than half of the $1.5 million he’s reported raising.

Rep. Roy Blunt (R-Mo.) boasted Thursday of raising $2.2 million for his Senate run in the last quarter, besting his Democratic opponent, Missouri Secretary of State Robin Carnahan, by almost $700,000.

Blunt's camp made the announcement first via Twitter, calling it his "largest quarter of the campaign."

Soon after, the campaign blasted a release to reporters noting it had more than $4.5 million cash on hand. Blunt received money from 5,000 individual donors in the second quarter. It's also spent almost $1.1 million since March 31, according to its disclosure report.

Carnahan, meanwhile, had her "best quarter to date."

She raised $1.55 million from 30,000 donors and now has $3.63 million banked, according to her campaign. She had a lower burn rate, spending $760,029 in the last three months.

Blunt spokesman Rich Chrismer said their fundraising figures are a sign that Missouri voters are rejecting Democratic policies.

"It is so clear to a huge and growing number of Missourians that the Carnahan, Pelosi, Reid and Obama policies are a disaster for jobs, the economy, healthcare and energy," Chrismer said in a statement.

A Carnahan spokesman said voters have had "enough" of Blunt.

"Missourians have had enough of Congressman Blunt's 14 years of wasteful spending in Washington and that is why he has been forced to go on TV early in the closing weeks of his primary fight to defend his record of bailouts, earmarks, and deficit spending," Carnahan spokesman Linden Zakula said in a statement.

Rep. Rob Simmons (R-Conn.), who suspended his campaign for Senate after the state Republican convention in May, said in an interview Wednesday he is considering getting back into the race. 

“I haven’t made any final decisions,” Simmons told the Hartford Courant’s Rick Green. “I’m getting a lot of phone calls from people. Six weeks ago, the convention was over and I was very disappointed. My staff was despondent. My family was stunned.”

At the state party convention, former World Wrestling Entertainment CEO Linda McMahon (R) won the party’s endorsement, but Simmons won enough delegate support to keep his name on the ballot. 

Because McMahon is largely self-funding her bid, she has a formidable cash advantage. But Simmons still has close to $1 million in his campaign account. 

The Republican primary is Aug. 10. 

The West Virginia Republican Party is continuing a newspaper ad campaign it began Wednesday targeting Gov. Joe Manchin (D). 

The state party took out full-page ads in several Charleston newspapers linking Manchin to President Obama and Senate Majority Leader Harry Reid (D-Nev.).    

“This is just the first in what we anticipate will be a series,” state party Chairman Doug McKinney told the Charleston Gazette. “We think these are questions the governor needs to answer if he wants to run for the Senate.” 

The ads push Manchin to publicly break with the Democratic leadership on cap-and-trade and healthcare, asking “Why are you so eager to quit your job and stand with the liberal Washington Democrats?”

Manchin is an opponent of the president’s cap-and-trade proposal.

A special session of the West Virginia legislature opens at noon Thursday, and lawmakers are expected to approve a bill that would allow Manchin to call a November special election to fill the seat of the late Sen. Robert Byrd (D). 

Manchin is expected to name an interim replacement for Byrd by 5 p.m. Friday and announce his own intentions for the seat shortly after. It’s widely anticipated that Manchin will run in a November special election. 

On the Republican side, Rep. Shelley Moore Capito is the party’s best chance to defeat Manchin, but under current state law she would have to resign her House seat to run in a November special election, something she is unlikely to do. 

Illinois Senate candidate Alexi Giannoulias (D) struggled to raise money in the aftermath of his family bank’s collapse in April.

Giannoulias has raised only some $900,000 since March 31 — the bulk of it in June. His Republican opponent, Mark Kirk, collected close to $1 million that same month. And Kirk was dealing with his own scandal — the fallout from inaccuracies in reporting his Navy service record at the time.

Giannoulias raised less than half of Kirk’s total, and the Republican now has almost a four-to-one cash on hand advantage.

“We are confident we are going to have the resources we need to compete,” a Giannoulias spokeswoman told Bloomberg.

Democrats were obviously concerned about Giannoulias’s numbers. Vice President Joe Biden and several others administration officials traveled to Chicago in the second quarter to help Giannoulias raise money. Other than Biden, Giannoulias got help from Education Secretary Arne Duncan, White House Deputy Chief of Staff Jim Messina and President Obama’s former campaign manager, David Plouffe. White House advisor David Axelrod is slated for a Giannoulias fundraiser on July 25.

Former Massachusetts Gov. Mitt Romney's political action committees have raised more than $1.8 million combined in the second quarter.

The political action committee (PAC) of Minnesota Gov. Tim Pawlenty, a potential 2012 GOP presidential candidate, took in close to $724,000 last fundraising quarter.

Freedom First PAC raised $723,801 between April and June of this year, and its total cash on hand is at $939,413. The committee spent $83,806 on state and national campaigns in that time frame.

Observers are scrutinizing the fundraising reports of several to judge the strength and vibrancy of their donor bases heading into the midterm elections and looking forward to the 2012 presidential campaign.

Former Massachusetts Gov. Mitt Romney's (R) Free and Strong America PAC took in $3.5 million in the first half of 2010, and received about $1.5 million in the second quarter, more than any other potential GOP presidential contender with a similar committee.

Former Alaska Gov. Sarah Palin's (R) PAC took in $865,000 in the second quarter and has raised about $1.3 million this year. Mississippi Gov. Haley Barbour's (R) PAC has received $278,000 through May.
