I want to make sure that I get this boiled down as simply as possible...
Some believe (i.e. CNN) that there are enough votes out there to pass this thing if we put it on the floor today. However, Boehner says that there aren't enough votes, so he's not even going to put it on the floor unless the President is willing to negotiate. Boehner is most likely unwilling to put it on the floor knowing that it probably would pass (because there are at least 18 Republicans willing to hop the aisle to put an end to this today), and if it did, it would make him and the rest of the House Republicans look stupid.
So, Boehner goes out there yesterday and says that the President is unwilling to negotiate. Once he does, he'll put whatever the negotiate out on the floor. I presume the logic, based on the McConnell/Paul soundbyte, is that they don't want to look like they got nothing out of all of this mess, so he'll press hard to get something.
The President goes out there today and says that if they put the bill on the floor today, and it fails, he'll negotiate.
So, ball seems to be in Boehner's court?
