The endorsement by the 2008 GOP vice presidential nominee, a longtime darling of conservatives, was intended to blunt Senator Ted Cruz’s surging challenge to front-runner Trump among right-leaning Iowa Republicans. Thirty-three percent (33%) of conservative voters think Palin’s endorsement will help Trump, while just as many (34%) say it will have no impact. Only 22% feel the endorsement will hurt his candidacy.

Among all likely voters, on the other hand, 21% say Palin’s endorsement will help Trump in the GOP race, while 30% believe it will hurt him. Thirty-seven percent (37%) say it will have no impact. Twelve percent (12%) are not sure. But then only 33% have a favorable opinion of the former Alaska governor, including 12% with a Very Favorable one.

Fifty-nine percent (59%) of Republicans, however, hold a favorable view of Palin versus 38% who view her unfavorably. This includes 25% with a Very Favorable view and 15% with a Very Unfavorable one. Her overall favorables are down only slightly from the summer of 2011, but 80% of GOP voters viewed Palin favorably in November 2009.
