On the republican side, those voting yea are almost always the old McCain crowd. What the right calls “RINOs” or republicans in name only. That’s not surprising, they’re also the group funding wars, voted for the initial spy bills, etc.

What’s more surprising is the split in IL between Duckworth (yea) and Durban (Nay). Usually you don’t see states splitting too much. Tennessee was all Nays for instance.
