The White House is preparing late this week to aggressively go after Senate Minority Leader Mitch McConnell (R-Ky.) and his GOP colleagues on financial reform.

A Democratic party source said Thursday evening that the White House was preparing to take an "aggressive stance" against Senate Minority Leader Mitch McConnell (R-Ky.) over Senate Republicans' vocal opposition this week to a financial regulatory reform bill set for debate on the Senate floor.

Democrats released a new video Thursday night to that end seeking to portray McConnell as parroting talking points that Frank Luntz, a GOP pollster who specializes in word choice, had recommended to Republicans in the financial debate.

The party source said the videos were only the opening salvo in an effort to take aim at McConnell and the GOP, with ads coming next, signaling a ramped up debate on financial reform.

McConnell took to the Senate floor on Tuesday to denounce the bill that'd been crafted by Senate Banking Committee Chris Dodd (D-Conn.) in recent months, arguing that the bill would only perpetuate bailouts, and do little to solve "too big to fail" financial institutions.

The partisan rancor came after Dodd abandoned bipartisan talks on the bill, which he'd pursued with the committee's Republicans, particularly Ranking Member Richard Shelby (R-Ala.) and Sen. Bob Corker (R-Tenn.).

"McConnell's arguments that the Democrat's plan for Wall Street reform will perpetuate bailouts is pure fantasy cooked up by Frank Luntz in a right wing focus group - and bears no reality to the legislation or Mitch McConnell and the Republican Party's longtime efforts to shill for Wall Street and its lobbyists," the Democratic Party source said. "If Mitch McConnell wants to look foolish and to look like the bag man for big banks that he and his colleagues are - we're glad to help."

Dodd filed the bill on the floor on Thursday evening, according to a tweet from a committee spokeswoman, setting up what's sure to be a contentious debate over regulatory reform in coming weeks.
