Speculation abounds, from The NY Times on down (or is it, on up?):

The Obama administration has informed Democratic Congressional leaders that President Obama and Speaker John A. Boehner were starting to close in on a major budget deal that would enact substantial spending cuts and seek future revenues through a tax overhaul, Congressional officials said Thursday.

In the meantime, it looks like the House Cut-Cap-Balance Bill will come up for a vote on closure this Saturday.  Protein Wisdom (h/t Pasadena Phil) has a list of Senatorial contact information.  Most of them are lost causes, but perhaps these few could be influenced by public reaction:
