The campaign arm of Senate Democrats launched its first paid advertisement Tuesday, aiming to tie vulnerable Republican incumbents and upstart Senate challengers to GOP presidential front-runner Donald TrumpDonald TrumpTrump on ‘lock her up’ calls: ‘Now we don’t care’ Report: Russia hacked GOP but didn’t release info, intel agencies believe Trump: I’ll devote ‘zero time’ to ‘Celebrity Apprentice’ MORE.

The Democratic Senatorial Campaign Committee (DSCC) ad intersperses clips of some of Trump’s incendiary remarks — with a lot of foul language bleeped out — with clips of incumbents and House members running for Senate saying they’ll support Trump if he’s the party’s nominee.

Among those who make an appearance: Sens. John McCainJohn McCainUkrainians made their choice for freedom, but now need US help White House orders intelligence report of election cyberattacks Senate votes to elevate Cyber Command in military MORE (Ariz.), Rob PortmanRob PortmanSenate passes dozens of bills on way out of town Senators to Trump: Get tough on Russia over Ukraine John Glenn dies at 95 MORE (Ohio), Kelly AyotteKelly AyotteDem senator tears up in farewell speech Juan Williams: McConnell won big by blocking Obama Battle brews over Trump’s foreign policy MORE (N.H.), Richard BurrRichard BurrTop Intel Dem: Congress 'far from consensus' on encryption Trump must be an advocate for the Small Business Administration Dems pledge to fight Sessions nomination MORE (N.C.), Mark KirkMark KirkJuan Williams: McConnell won big by blocking Obama Battle for the Senate: Top of ticket dominates The untold stories of the 2016 battle for the Senate MORE (Ill.), Pat Toomey (Pa.), Roy BluntRoy BluntSanders: GOP blocked 'Trump proposal' to lower drug prices McConnell: We'll start Obamacare repeal on day one Could bipartisanship rise with Trump government?

Portman, Ayotte, Kirk, Toomey and Johnson all face tough reelection prospects in a presidential year, when turnout could favor Democrats. Kirk and Johnson are the most endangered of the bunch, while Portman, Ayotte and Toomey are running in hotly contested swing states.

Also in the ad are Reps. Joe Heck (Nev.), who is running for the seat being vacated by Sen. Harry ReidHarry ReidSenate passes dozens of bills on way out of town Staff shakeup begins at Dem campaign committee The Hill's 12:30 Report MORE (D-Nev.), and David Jolly (Fla.) and Ron DeSantis (Fla.), who are in a crowded primary running for the seat being vacated by Sen. Marco RubioMarco RubioSenate clears water bill with Flint aid, drought relief What Trump's Cabinet picks reveal House passes water bill with Flint aid, drought relief MORE (Fla.).

“Republicans running for U.S. Senate, running with Trump,” text from the ad states.

It then cuts to Trump saying: “What the hell are we doing?”

“Exactly,” the ad concludes.

The DSCC says the ad is the first in what will be a “sustained campaign” across television, radio and social media meant to tie Republicans running for Senate to the controversial GOP front-runner.

Democrats have a good chance of taking back the Senate in 2016 after losing their majority in the last cycle.

Republicans are defending 24 seats, compared to only 10 for Democrats. If Democrats net five seats, they’ll win back the Senate.

Many Republicans up for reelection are running in states President Obama carried in 2008 or 2012.
