I'll go against trend here. I find it highly unlikely that it is NOT extended. Obama really will start his second term with a "tax increase"? No. When this came out it was supposed to be temporary and I was positive it wouldn't be; I was right (it was extended), and I think I'm right this time also.
I think it depends on how bitter Repubs are over ending the Bush cuts for tippy-top earners, and on the shape of any overall deal, if there even is one.
They haven't been shy about holding the economy underwater over the last 4 years, and I doubt their attitude has changed much. The power of wealth is enhanced in depressed economies, and, well, there it is.
I'll pay my 2% willingly if Mitt & his peers are made to pay the same rates as the rest of the lesser top 1%... The vast majority of Americans would consider themselves blessed, not put upon, to pay big taxes on big money.
Too bad a guy can't just sign up to pay 38% in federal taxes on $1M/mo- there would be a lot of takers, bet on it.
