Given who these people are, I am expecting a scorched earth from the demonrats. If they lose their majority, then they have nothing to lose. When the Bush marginal tax rates expire, the dims will get a tax increase without having to cast a vote. All they have to do is wait out the clock. All this talk about raising taxes on the 250K and higher crowd is just so much talk.
The tax code is more about control of the population than raising funds and this current crowd is big on controlling the population.
Letting all of the Bush tax cuts expire was in Obama’s plan all along - it was how he planned to pay for ObamaCare. The $250K was an empty promise to the middle class.
