Lance Armstrong and Sheryl Crow Break Up Over George W. Bush?

As is often the case when celebrity couples part company, there has been an enormous amount of press coverage concerning the Lance Armstrong/Sheryl Crow split.

But the Star is reporting a possible political cause for the engagement halt. There's speculation that the root of the rift may have to do with President Bush.

No, Crow doesn't have a crush on the prez. Quite the contrary. The singer has been public about her opposition to Bush's policies.

Many of us have a less than fond remembrance of her highly visible, much discussed "War Is Not the Answer" T-shirt.

Well, it turns out that Armstrong is actually a Bush backer. The famed cyclist went biking with the commander in chief last summer.

According to a friend of Crow, Armstrong was a Bush backer to the max.

"Sheryl said Lance didn't just support Bush, - he'd go off and fight if the president asked him to," the friend said.

The Left Coast Report says, Poor Sheryl, how will she ever find someone who shares her hatred of Bush in a place like Hollywood?
