It's not that weird though if you look at the general political situations across the world. It'll probably just continue as you expect it to; you know, Democrats retaining power, just not as popular as they should be while Republicans flounder until they reform and make some gains again. Nothing will really happen I don't think, it'll just be a restless, impotent period.
The arc of politics is long, but it tilts towards the Dems. Simply put: The first rule of Democracy is it's a numbers game. Republicans have created a constituency far more rightist then the rest of the country, and Demographics will increasingly tilt Democrat. The Democrats won the house popular vote, it's only through massive gerrymandering in state offices, which was accomplished by luck timing the Tea Party surge with the census. It has bought them some time, but they, even now, continue to lose support. Obama may not be very popular (His approval/disapproval is running a -1%), but congress is reviled.
Anyway, Ted Cruz is staging a hilariously off-topic Filibuster that won't have the ability to stall time, as when the bill is due to be voted on, he'll be booted off. He has apparently gone 21-hours, fourth longest on the records, on the faux-Filibuster, on subjects as varied as Ayn Rand to Dr. Seuss, from Ashton Kutcher on "Duck Dynasty" to Nazi comparisons, and there was a Darth Vader impression at some point. His Filibuster will not succeed even a delay of voting, having been staged a while before it is up.
