Subject: Why can't reps pass the CR with only 51 votes
I still haven't found the answer to this yet. It's been said here that the republicans could override the 60 vote rule to pass the CR with only 51 votes, but is that really true? My google-fu is failing me.

So, is it only that they don't want to override the 60 vote rule, or that they truly can't in this case?
