Sure, I can try.
Dems have little incentive to give in on their Medicaid and other budget demands after Tuesday's results and polls showing that Republicans are largely being blamed (and rightfully so, imo) for the shutdown.
Republicans have a myriad of options, but with no singular play that makes everyone in the big tent happy. Even removing the filibuster which gets rid of Dem opposition there is not a 100% chance that all Republicans agree to vote on cutting Medicaid among other issues with the budget. On the other hand, you have those that do not want to agree to keep Democratic demands in the spending budget. Removing the filibuster also opens a can of worms where there can be more legislation that purple area R's don't want to have their name associated with as the midterms near. On top of that they have to come up with a budget(s) that the president will sign. Especially, with a president who does not like to appear weak or giving in to the opposition party.
