GOPres candidates and the Immigration bill

I think that the failed Immigration bill has real potential to provide real separation in the race for the '08 GOP nomination. Here's what the individual candidates are saying about the bill's demise. Article - News - Immigration in the campaign.

In particular, a recorded vote on an actual piece of legislation takes the issue to the next level of campaign significance, because candidates can no longer dodge and duck and spin their theoretical views on the issue--especially those who had to cast a vote on the bill.

I believe that in consequences to date for supporting this legislation will pale in comparison to the injury going forward. I believe the GOP base will seriously hold to account the campaigns of McCain and Brownback.
