Let's say that in this hypothetical scenario, the Dems manage to do a bit better in 2006. Better candidates, worse GOP performance and scandals, lead to a even larger blue wave.
2006 Senate: 54 D (+10), 45 R (-10), 1 IND (=)

But the blue tsunami is then followed up by an even larger tsunami (than OTL) in 2008 in the wake of the recession, with better Dem performances.

These elections have basically gave Dems supermajorites in Congress and State. The 111th Congress looks it would be the high mark of Dem majorities before going down in the next few years. Dems also have enough senators, house members, and state legislatures to potentially amend the constitution too. How would it impact bills, politics, the Dem President (Can be anyone like Obama, Clinton, Edwards, Biden, etc.), in the next few years?
