A few more details on the marriage vote, from AP

According to AP, 45 Republicans and three Democrats voted to keep the measure alive. Six Republicans joined 43 Democrats and one independent in opposition. Of course, AP doesn't actually mention their names, duh.

I'm still trying to figure out who the sixth Republican is...

Ah ok - someone just mentioned in the comments, it had to be Snowe - so the following Republicans crossed party lines to help us out:

NO - VOTED AGAINST STOPPING FILIBUSTER (Probably does mean that they oppose the amendment)
Sununu - R-NH (I know, very weird, but I swear I heard it - will double check)
Collins - R-ME
Chafee - R-RI
Mccain - R-AZ (interesting)
Campbell - R-CO
Snow - R-ME
