The Boss performed at an Obama campaign rally in Ohio on Thursday (18Oct12) just hours after posting his support for the incumbent on his website.
The rocker wrote: "The election is coming up on all of us and we all have strong feelings about it. I've been getting asked a lot about where I stand, so for those who are interested, here goes.
"This presidential election is different than the last one because President Obama has a four-year record to run on. Last time around, he carried with him a tremendous amount of hope and expectations. Unfortunately, due to the economic chaos the previous administration left him with, and the extraordinary intensity of the opposition, it turned into a really rough ride. But through grit, determination and focus, the president has been able to do a great many things that many of us deeply support."
Obama's most high-profile supporters include George Clooney, Sarah Jessica Parker and Gwen Stefani, who have each hosted fundraisers for the President, and Eva Longoria and Scarlett Johansson, who spoke at the recent Democratic National Convention.
The leader's chief rival, Mitt Romney, also has plenty of celebrities on his side - he has had public endorsements from Republican rockers Kid Rock and Ted Nugent and fellow Mormons Donny and Marie Osmond.
