A new Gallup poll shows McCain has a 67 percent favorable rating, a figure matching his all-time high favorable rating in February 2000 when he was running for president for the first time.

His rating is 10 points higher than it was last winter. His approval dipped to 41 percent as his campaign appeared to be foundering, Gallup said. Then after his win in the New Hampshire primary his favorable rating began to climb and continued to do so, Gallup said.

Among the Democratic candidates, Barack Obama has a favorable rating of 62 percent, a number that has been stable for the Illinois senator since January, Gallup said.

Rival Hillary Clinton's favorable rating at 53 percent is the lowest of the three White House contenders. Even so, her latest favorable rating is Clinton's highest rating since October of last year.

The New York senator's favorable rating was highest at 67 percent in December 1998, as her husband, then-President Bill Clinton, was being impeached.

The survey is based on a March 14-16 poll of 1,025 national adults. The maximum margin of sampling error is plus or minus 3 percentage points.
