In an MSNBC interview Tuesday morning touting the release of his campaign's new TV ad, Rep. Kendrick Meek (D-Fla.) didn't sound like a candidate holding onto the possibility of a campaign visit from President Obama before November.

Meek, who is locked in a three-way Senate contest with Republican Marco Rubio and Gov. Charlie Crist (I), said on MSNBC's "Morning Joe" that it's important for the next senator from the state to "have a working relationship with the president." 

But as for a potential campaign visit from Obama, Meek said, "If the president wants to come to Florida, he's welcome to come to Florida." 

In his first TV ad of the general election, Meek takes some shots at his two opponents without mentioning either by name. The congressman runs through a litany of policy positions that he says make him "different" from Rubio and Crist, claiming, "with three of us running, you should know what makes me different." 

The ad, produced by the Democratic firm Murphy Putnam, features Meek in half a dozen different locales, from riding a boat in the Everglades to sitting on a bus with senior citizens. In the 30-second spot, Meek calls himself "the only one who's against privatizing Social Security," and the "only one who took on George Bush."

Meek's ad comes as Crist also launches his first TV ad of the general election, trying to paint himself as being above party politics.  

"How do we get results for Florida?" Crist asks in the ad, flanked by letters spelling out the words "Democrats" and "Republicans." 

"By putting aside our differences and putting people ahead of politics," he concludes as he rearranges the letters to spell the word "Americans."
