Obama's endorsement would also make 30% of voters less likely to vote for a candidate, while the endorsement of the former half-term Alaska governor would turn off 34%. Palin, then, is more divisive than the president -- she would both sway and repel more voters than Obama, the poll shows.
Quinnipiac also reports the president's favorable ratings to be considerably higher than Palin's. Forty-nine percent of voters have a favorable impression of Obama, while only 35% have a favorable impression of Palin.
The poll's measure of Obama's job approval rating -- 44% -- is the lowest Quinnipiac has ever reported for Obama. Recent polls by Fox News, ABC/Washington Post, and Gallup also showed the president's approval rating at an all-time low.
