The Obama campaign tonight aired its first national TV ad of the election cycle - a 30-second spot on the MTV Network that features actress Sarah Jessica Parker plugging President Obama's record and soliciting donations for a campaign sweepstakes.

"OK, the guy who ended the war in Iraq; the guy who says you should be able to marry anyone you want; the guy who created 4 million new jobs.  That guy - President Obama - and his wife Michelle are coming to my house for dinner on June 14th," Parker says to camera.

"And I want you to be there too. But, you have to go to JoinObama.com for a chance to win and the contest ends tomorrow night. So go right here right now because we need him and he needs us."

The spot, an appeal to younger Obama supporters, aired three times tonight during the 2012 MTV Movie Awards, a campaign official said. It comes as part of a major fundraising push to kick off the month of June.

A similar grassroots fundraising contest for an event last month at actor George Clooney's Los Angeles home brought in millions of dollars above what was raised from high-dollar ticket sales, according to the campaign.

On Friday, Vogue editor-in-chief Anna Wintour, an Obama bundler and co-host for the June 14th event, starred in a campaign web video pushing the contest.

"Sarah Jessica and I have our own reasons for supporting President Obama. And we want to hear yours. So please join us," Wintour says. "Just don't be late."

Republicans have criticized the star-powered fundraising appeals to grassroots donors as "out of touch," given the state of the economy.

"The Obama campaign showed once again how out of touch they are, releasing a fundraising contest featuring Vogue chief Anna Wintour the same day as a dismal jobs report highlighted how millions of Americans continue to struggle," said Republican National Committee spokeswoman Kirsten Kukowski.
