ST. PETERSBURG, Fla. - Mocking his opponents' economic agenda, President Obama says Republicans are pushing tax cuts as the prescription to cure the ailing economy, "help you lose a few extra pounds," and even "help your love life."

The president unveiled the new quip Friday, but today he got a unique response as he kicked off his two-day campaign tour through Florida.

"It doesn't help!" shouted a man of his lacking love life.

Obama, seemingly caught off guard by the joke, laughed in response. "You tried those tax cuts, huh?" he asked.

"Actually it does help when you give it to folks who need it," the president continued, never missing an opportunity to push his economic proposals. "But I don't believe, and you don't believe, that another round of tax breaks for millionaires is going to bring good jobs back to our shores, or pay down our deficit."

Two days after formally accepting his party's nomination, the president reflected on the convention, suggesting former President Bill Clinton should be given a new cabinet position after his rousing speech.

"After he spoke, somebody sent out a tweet - they said, you should appoint him Secretary of Explaining Stuff," Obama told the crowd of 11,000 gathered in the sweltering heat at St. Petersburg College-Seminole Campus. "Although, I have to admit, it didn't really say 'stuff.' I cleaned that up a little bit."

Obama is spending the weekend on a campaign bus tour through the Sunshine State, part of his post-convention battleground state swing.

After his rally in St. Petersburg, the president rolled through Tampa, Fla., the site of the GOP convention two weeks ago, where he stopped for lunch at a Cuban sandwich shop.

"At their convention, they were more than happy to talk about everything they think is wrong with America, but they didn't say much about how they'd make it right. They want your vote, but they don't want you to know their plan," Obama said.
