President Obama's re-election campaign and the Democratic Party report they raised $68 million in the final three months of 2011.

Obama campaign manager Jim Messina told supporters in a Web video Thursday that the president's campaign was off to a "pretty good start."

According to Messina, 1.3 million Americans donated money, with 583,000 people giving money to the campaign this quarter and more than 200,000 giving to the campaign for the first time.

Still, Messina was careful to avoid giving the impression that Obama's re-election was a done deal.

"The only way this thing works is if each of you take a piece of the campaign and help build the best grassroots campaign in modern political history," he admonished supporters.

"That means giving now and giving as much as you can between now and when Barack Obama wins in November," he said.
