From there, the ad pivots to CPAC, an annual convention of conservative activists and politicians.

"So what's he going to say to win over this crowd?" the ad continues, before rolling a montage of moments from earlier iterations of the conference. Clips include Rep. Michele BachmannMichele BachmannBachmann: Muslim immigrants trying to undermine Western civilization Religious leaders pray over Trump in Oval Office 'Real Housewives' producer 'begging' Conway to join cast MORE (R-Minn.) saying the president "ushered in socialism," Sen. Rand PaulRand PaulCurtis wins GOP primary for House seat vacated by Jason Chaffetz Glimmer of hope in bipartisan criminal justice reform effort Trump barrage stuns McConnell and his allies MORE (R-Ky.) calling for the abolishment of the Department of Education and for individuals to be able to opt out of Social Security, and radio host Rush Limbaugh telling the crowd he wanted to see the president fail. The CPAC crowd is also shown cheering enthusiastically at many of the moments.

"Mitt Romney: What will he say today?" the ad concludes.

"The bottom line is that Mitt Romney keeps going further to appeal to the most extreme, far-right-wing conservatives in the country ... the Donald Trumps, Ann Coulters and Michele Bachmanns of the world," the DNC said in a statement.

The ad is the latest in a stream of Web videos from Democrats hitting Romney after his tough losses. On Thursday, the DNC issued a Web video challenging Romney's attacks on Republican challengers Newt Gingrich and Rick Santorum — whom Romney painted as Washington insiders — by pointing out that Romney was spending the day campaigning with industry lobbyists in the nation's capital.
