VIDEO: Democrats launch new TV ad attacking Senate GOP on Wall Street

Democrats went on the attack against Senate Republicans on Wednesday, launching a broadside on financial reform they vowed to maintain through the fall.

The Democratic National Committee (DNC) launched a new national television ad targeting all 41 Senate Republicans who voted earlier this week against allowing debate to begin on Wall Street reform legislation.

The ad, titled "Risky Business," seeks to tie the GOP to large financial institutions, arguing that they are siding with Wall Street over "Main Street."

The commercial, which will run through next week in Washington and on national cable, comes after two days in which Senate Republicans, joined by centrist Democratic Sen. Ben Nelson (Neb.), voted to block beginning debate. Senate Majority Leader Harry Reid (D-Nev.) has scheduled a third vote for Wednesday amid signs that the GOP block might be cracking on the issue.

But Democrats warned Wednesday that they plan to make an issue of Republicans' vote on the bill throughout the election cycle this year.

"Any Republican who continues to stand with Wall Street instead of our families should expect that we’ll make sure that their constituents hear about it from now till November. ‘Risky Business’ refers to the irresponsible practices of Wall Street banks that got us into this mess, but if they keep standing with these banks, Republicans may well find that it refers to their electoral prospects as well,” said DNC national press secretary Hari Sevugan.

Republicans, for their part, have said Democrats lack credibility on financial reform, pointing to instances in which Democrats' claims about their stimulus and healthcare bills haven't played out.
