In the aftermath of the LOOOONG US election campaign season, I wonder if celebrity endorsements make a difference in presidential elections. There certainly have been a lot of them this year, for both candidates. Actors, comedians, athletes, talk show hosts, super models. And there’ve certainly been a fare share of musicians joining each camp: Trace Adkins, Charlie Daniels, Meat Loaf, and Donny and Marie Osmond are among those backing Mitt Romney; and Mary J. Blige, Mariah Carey, Aretha Franklin, Elton John, Beyonce, and Barbra Streisand are on President Barack Obama’s bandwagon. And there are many more.

Yesterday, Katy Perry shared a photo taken with President Obama at a recent campaign stop. And as she said on twitter , this might be the cutest picture ever. It’s Katy and the President with her 91 year old grandmother, Ann Hudson.

For Katy, showing up at a rally wasn’t just because it was a good photo op. She spent a good deal of time out on the campaign trail this fall. This fan video shot was shot at an Obama rally in Las Vegas last month.

While Katy was out stumping for President Obama, Kid Rock has been speaking (and singing) out in support of Mitt Romney. And he’s happy that “Born Free” has become a sort of campaign song for the Romney-Ryan ticket.

And earlier in the campaign, Meat Loaf surprised everyone by making his first ever political endorsement, coming out in support of Mitt Romney.

But the most outspoken musician campaigning this year is probably Bruce Springsteen.

He spent the final day of the 2012 campaign with the President in Columbus, Ohio and Des Moines, Iowa. He also gave a rousing speech that day at a rally in Madison, Wisconsin.
My crystal ball is a bit cloudy, so I can’t predict who’s going to be the winner. All I can say is that some musicians and entertainers are going to be singing the “White House Blues” tomorrow.
