Former President George W. Bush expressed skepticism of the current push for immigration reform, warning Republicans not to adopt a measure just because they hope it will help them at the polls, although he still believes that reform is necessary.

“I think the atmosphere, unlike when I tried it, is better, maybe for the wrong reason,” Bush told The Huffington Post’s Jon Ward. “The right reason is it’s important to reform a broken system. I’m not sure a right reason is that in so doing we win votes. I mean when you do the right thing, I think you win votes, as opposed to doing something that’s the right thing to win votes. Maybe there’s no difference there. It seems like there is to me though.”
