@hawkeye10,
President Obama has been pretty consistent in saying taxes should be raised for people with income greater than $200k so I don't think you have a cause to complain there. When he let the Bush tax cuts expire, he negotiated with the Republican House to keep some of the low end cuts but had to let the high end go to a higher number, I think $400k.
I think this is something different. The President is no longer constrained by any hope of negotiating, so he can just say what he wants. I was listening to a radio news article a few weeks ago that talked about negotiating strategies. They tasked two groups with selling a CD. The first group they told that if they couldn't sell the CD, they could get a backup price (low, like $1). The second group had no backup available. The second group negotiated more aggressively and got a better average price for their CD's than the first group. The two suggested theories were that the backup made the first group more willing to settle and that the low price set an expectation as to the value of the CD in the first group's members.
When the President was elected, the Democrats were the first group trying to get something done, the Republicans were the second group with no fallback position and nothing to lose by going nuclear on every issue. Now the tables are turned. President Obama has no fallback position. There is no half-loaf solution available for him. The Republicans are in the position of having to actually govern with Obama in the big chair and with the Democrats completely willing to filibuster in the Senate. I half way expect the Democrats to go a nuclear, scorched Earth policy for the next two years.
I also expect the President's tax proposal to go nowhere, but I don't think historians will even make note of the suggestion.
