As far as I've ever been able to tell (and I have no good data to back this up, mostly because I don't feel like spending a lot of time researching this post), Americans tend to gravitate to the center without necessarily knowing what that means. That might be just as unfair as the Obama=center-right meme, but it feels true. I even thought I was moderate until I started to really learn what words like "liberal," "conservative," (politically) "left," and (politically) "right" meant.
So, what the heck, let's call Obama center-right. Closing Gitmo? Fine, let's call that a center-right position, and pretend that the real centrist position is fixing the FISA courts (nudge nudge, wink wink). Putting people to work through a public works program that simultaneously repairs our infrastruture? Sure, what the heck, that's a center-right position. Raising the minimum wage and extending unemployment, that's the real centrist position.
What do you think, would that work?
