TAMPA, Fla. - Senate Minority Leader Mitch McConnell, who has been prosecuting a two-year case against Barack Obama's reelection, charges in his Republican Convention speech Wednesday night that the president has spent more time practicing for a golf tournament than fixing the nation's ills.

"For four years, Barack Obama has been running from the nation's problems. He hasn't been working to earn reelection. He's been working to earn a spot on the PGA tour," the sometimes tart-tongued McConnell says, according to excerpts provided to Secrets.

What's more, he adds, the president hasn't spelled out what he would do in a second term. "We know what the president's got on his iPod, but we don't know what he plans to do about a looming tax hike that could trigger yet another serious recession that would result in even more Americans losing their jobs. Ladies and gentlemen: America cannot afford another four years of this."

The Senate leader has been rapped by Democrats for being so tough on Obama and for his early-on public call to defeat the president. But those criticisms haven't quieted the Kentucky lawmaker. In fact his convention speech steps it up a notch.

"As we meet here tonight, America is suffering through an economic calamity of truly historic dimensions. Some are calling it the slowest recovery in our nation's entire 236-year history. To call this a recovery is an insult to recoveries," he says.

And of the policies the president has pushed so far, McConnell says that they are out of touch with the mainstream of American life and further damaging the economy.

"What this administration has in mind for America isn't a renewal, it's a great leveling out. It wants the kind of government-imposed equality that in a single generation transformed Western Europe from a place where for centuries high achievement and discovery and innovation were celebrated and prized, to a place where they have elections about whether people should have to work. Where they make promises they can't keep and write checks they can't cash."

McConnell also gives a full-throated endorsement to Mitt Romney. "When Mitt Romney looks down the road, he sees a country that's ready for a comeback. I firmly believe he's the man to lead it," says McConnell. On Tuesday, convention keynote speaker New Jersey Gov. Chris Christie was criticized by some for not giving a similar strong endorsement of Romney.
