It's unlikely. Most democrats oppose this (protectionism) and many republicans oppose it as well (anti-immigration stance). It's lose-lose for immigrants.
Regardless of whether politicians "support" it, I expect that most of them know that it's really good for the country in the long term. That's why I said that I hope Obama, who's been all about change, will have the brains (and the balls) to actually do the right thing.
