What happens when we win?

After the rout.

I agree with all of Chris's predictions to varying degrees. It really is pretty hard to predict what the Democratic Party will do, since their tactic over the past 2 years has been to hunker down and wait out the Bush Presidency, since he'll veto anything fun anyway.

In addition to the normal three axes in American politics (Economic, Foreign, Social), there's a fourth axis that could be described as Partisanship. For example, although Rahmbo is fairly conservative on most things, he's a hyper partisan and will always be first in line to try to fuck the Republicans. On the other hand, you've got a fair number of progressives like Kucinich who seem to enjoy telling Hoyer to get bent. So, once the Democrats have such a huge majority, and a President who will sign their bills, there'll be a wild and wacky period of inter-party alignment. My suspicion is that it'll end up being a fairly liberal working majority that ignores social issues and occasionally throws a piece of meat to corporate America. So: Yes on Universal Health Care, No on repealing DOMA.

Figuring out what the Republicans are going to do is easy. They'll probably fire Boehner, but even if they don't, they'll retreat to "Fuck you, that's why!" mode for the entirety of the Obama presidency. The House Republicans left standing after November will be the ones who are untouchable. If their districts are so conservative that they survive this election, then the only way they'll lose their seats is with a primary challenge from the right. And with such a large Democratic Majority (it's already larger than anything the Republicans managed from 1994-2006), they won't see any feasible way back into the majority. That means they have every incentive to screw with the Democrats, and none to work with them.

Which means the Democrats will be passing legislation by themselves, which is another reason they'll factionalize. Let's say we pick up 25 seats in the election. That'll make it 260 Dems to 175 GOP. That's an 85 seat advantage. But here's where they get bitchy. The GOP just decides that it's going to vote no on everything. Since all of their members are safe, and most of them are assholes, that bloc will hold.

So now you've got 260 Democratic Congressmen, of which 218 are needed to pass anything. Or, to put it the other way, only 43 Democratic congressmen need to be bought off by corporate lobbyists in order to stymie the progressive agenda. That's frighteningly possible, and the main reason why Kos has already made plans to wage a Jyhad against bad Democrats in 2010.
