here's a good Philadelphia Inquirer article on the political reaction to Santorum's comments. See Josh Marshall, Is That Legal, and even Andy Sullivan on the ugly nature of the comments directed to gays.
The phili article notes some of the things i've been wondering about; to wit, how are the repubs going to play this out. already, bush has called the senator an "inclusive" man. As Josh Marshall pointed out today, there are alot of words one could choose. Inclusive isn't one of them.
