Steelers owner endorses Obama

Barack Obama already had the Bus in his corner.

Now, he has the Bus's boss.

Former Pittsburgh Steelers fullback Jerome Bettis joined Obama for part of his bus tour through Pennsylvania. Today, Steelers owner and chairman Dan Rooney announced his support.

"True sports fans know that you support your team even when they are the underdogs. Barack Obama is the underdog here but it is with great pride that I join his team," Rooney writes in a "Dear Pennsylvanians" letter released by the Obama campaign.

"This is not something that I do regularly but as I listen to the candidates in this race, I am struck that we continue to hear about the problems and the same challenges that we have been talking about for decades. Protecting jobs here in Pennsylvania, breaking our dangerous and costly addiction to foreign oil, making health care accessible and affordable – these are neither new issues nor new ideas. And yet we have failed to make real progress," Rooney writes.

"As a grandfather and a citizen of this community I think Barack Obama’s, thoughtful, strategic approach is important for America. When I hear how excited young people seem to be when they talk about this man, I believe he will do what is best for them which is to inspire them to be great Americans."
