According to a new Rasmussen Reports national telephone survey, 29% of Likely Voters say an endorsement from the president is the one most likely to make them vote for a candidate.

But even more (45%) say Obama is the politician who makes them least likely to vote for a candidate he endorses.

As for the others on the list, 16% rate an endorsement by former President George W. Bush as the most likely to make them support a candidate, followed by former President Bill Clinton (15%), ex-Alaska Governor Sarah Palin (14%), New Jersey Republican Governor Chris Christie (5%) and Vice President Joe Biden (1%).

When it comes to an endorsement as a negative, 25% say one from Palin makes them least likely to support a candidate.
