In the new web ad entitled "Not Up to the Job" to be released Monday, the RNC reminds voters that Democratic National Committee Chairwoman Debbie Wasserman Schultz (Fla.) opposed Obama and backed then New York Sen. Hillary Clinton in the 2008 Democratic nomination contest.
The web video shows footage of Rep. Wasserman Schultz praising then candidate-Clinton and leading supporters in a chant of "Hillary."
The text then presents statistics about Florida's economy "four years later, under President Obama" including figures claiming a 9.9 percent unemployment rate in the state, 1.1 million new foreclosures and a 650,000 more state residents below the poverty line.
"In 2008, Debbie Wasserman-Schultz knew Obama wasn’t up to the job... Four years later, we all do," concludes the on-screen text.
Wasserman Schultz who assumed the chairmanship of the Democratic National Committee in 2011 is now one of the president's most visible and vocal public defenders.
Sunday on CBS's Face the Nation, the Florida lawmaker praised the president's economic proposals in his recent State of the Union address.
"Barack Obama is fighting for the middle class and working families and the tax code that makes it possible for everyone to be successful, Mitt Romney and the rest of the Republican field thinks we should extend tax breaks for the wealthiest, most fortunate Americans so they can do better," she said.
The RNC ad comes one day ahead of the GOP's primary in the Sunshine state.
