Washington (CNN) - One day after Senate Democrats' second attempt to open debate of a financial reform bill failed, the Democratic National Committee is out with a new ad slamming Republicans for not supporting the measure.
The 30-second spot launching Wednesday and airing on national cable comes as both parties seek to prove that their allegiance is to everyday Americans and not big financial institutions. According to an ABC News/Washington Post poll released Monday, 65 percent of the public supports stricter federal regulations on the way banks and other financial institutions conduct their business, with 31 percent opposed. A majority of people questioned in a CNN/Opinion Research Corporation poll conducted last month also favored greater government regulation of banks and other financial institutions.
"Tell republicans: If they side with Wall Street over Main Street, you won't be siding with them," the DNC's ad says.
On Monday, Republican National Committee Chairman Michael Steele argued that it's Democrats who are siding with Wall Street.
"Senate Democrats stood with Wall Street by attempting to move forward with a bill that creates a permanent bailout for irresponsible financial firms, institutionalizes 'too-big-to-fail,' and does nothing to reform Fannie Mae and Freddie Mac, organizations that were at the heart of the financial crisis," Steele said in a statement.
"So instead of working with Republicans to responsibly reform financial regulations, Harry Reid decided that it's better to have no bill at all, creating a partisan side show instead of holding Wall Street accountable," he added.
