President Obama joked during his speech at the White House Correspondents Association dinner in Washington that Saturday was the 10-day anniversary of his first 100 days.

Speaking of the first 10 days of the rest of his presidency, Gallup reports today that Obama's approval rating average since the 100-day mark is 66%, 3 points higher than the average rating of his first 100 days.

Perhaps of more importance to Obama's re-election -- which is still three and a half years away -- is that 25% said they would definitely vote for him in 2012, while 28% said they would probably vote for him. That 53% total includes 90% of Democrats, 46% of independents and 16% of Republicans.

On the other side, 25% said they would definitely not vote for Obama, and 12% said they probably would not.

A similar question was asked in June 1994 and January 1995, and both surveys found just 11% saying they would definitely vote for Bill Clinton in 1996. Clinton would go on to defeat Bob Dole by more than 8 points in the popular vote and 220 electoral votes.
