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.”

But Bush supports immigration reform, in principle. “In 2006, I gave the first-ever primetime presidential address on immigration,” he wrote in his memoir, Decision Points. ‘We’re a nation of laws, and we must enforce our laws,’ I said. ‘We’re also a nation of immigrants, and we must uphold that tradition, which has strengthened our country in so many ways.’”
