Democrats moving right on immigration?

In an October 31, 2007 post to New America Media (http://news.newamericamedia.org), Roberto Lovato argued that

The real threat looming on the electoral horizon is that more and more Democrats are joining Republicans in capitulating to the public antipathy against immigrants.

I have noticed evidence of this in the recent presidential debates. When faced with the question of allowing driver's license for undocumented workers, all of the candidates gave a quick "no" except for O'bama, and he was clearly uncomfortable with offering any real hope on this issue.

I'll have more to say about the issue of driver's licenses later, but I merely note the mounting swing to the right among democrats for now.
