Obama campaign hits Romney on what he 'didn't say' in Tampa

"On Thursday night, Mitt Romney gave the biggest speech of his campaign — a chance to tell America what he’s done and what he might do as president. But Romney offered no tangible ideas to move the country forward — not a word about his plans for the future," said text released with a new campaign video.

The video, titled "Say," goes on to blast Romney for not discussing his proposals on the tax code, Medicare and education, while at the same time slamming the former Massachusetts governor's policy positions.

"He didn’t talk about his plan to give trillions in tax cuts to big corporations and the wealthy paid for by the middle class; or his plan to end Medicare as we know it by guaranteed benefits with a voucher system. He didn’t talk about his budget, which could cut funding for K-12 education and Pell Grants for college by 20 percent," continues the statement.

The more than two-minute-long video also accuses the GOP nominee of slashing funding for renewable energy and missing an opportunity to discuss his plan for withdrawal from Afghanistan.

"Thursday was Mitt Romney's big night to tell Americans his plans for moving forward, yet he chose not to … when you learn about the Romney plan, is it any wonder he don't have much to say?" says a narrator in the video.

Obama's senior campaign adviser, David Axelrod, echoed the campaign's message on MSNBC's "Morning Joe" Friday, criticizing Romney's acceptance speech as full of "snarky" attacks against the president and gauzy proposals without specifics. 

The Romney campaign, on the other hand, was touting the Republican presidential contender's speech as a success on Friday morning.

Ann Romney made the rounds on morning television, praising her husband's performance for showing voters “the deepest part of his soul.”

"This is how I see him; this is the emotional part of him that I know so well," she told NBC's "Today" show. 

Romney was back to campaigning Friday, hitting back against Obama's record while in Lakeland, Fla.

"Paul Ryan and I both spoke to the American people about what we will do if we become president and vice president. And I contrast that with what the president said four years ago when he was candidate Barack Obama. He got up and made a number of promises in Denver with the Greek columns behind him. He doesn’t remind us of the Greek columns because he had said that he would cut the deficit in half. Measure him on that. How did that work out?" said Romney.
