To little effect, it seems:
According to a recent YouGov survey, the effect of celebrities weighing in on political issues is surprisingly small.
Just 7 percent of respondents said that a celebrity endorsement has ever made them support a candidate and 11 percent said they reconsidered their position on a political issue based on a celebrity’s opinion before.
Democrats seem to be more receptive to celebrities getting involved in politics, while the majority of Republicans think that celebrities should stay out of a politics.
Either way, it seems like any public figure taking a stand these days risks rubbing people the wrong way – YouGov found that 51 percent of respondents have, in the past, formed a negative opinion of a celebrity based on his or her political positions.
