..because they know Republicans will block them and they want to muddy the deficit issue for the 2012 election.
My argument AGAINST these taxes would be different than the standard arguments that are popular here and that talk radio has repeated a million times(which are not working anymore BTW) :
If tax increase on the rich are such a great idea then why didnt Obama and Pelosi do them in 2009 and 2010 when they had 59 Senators and only needed 50 to pass it like they did the Obama-care budget reconciliation? In fact they could have raised taxes on the rich and extended some of the Bush middle class tax cuts and still used reconciliation as long as it's scored deficit neutral, and still protected 9 Democrat Senators who could vote against it. Why (Democrats) did you wait till Republicans got power to demand what you could have done yourselves easily without them but what you (Democrats) refused to do yourselves?
Hopefully by now you understand why they didnt raise taxes themselves: to keep this an issue for 2012. Republicans are losing on this issue which is sad, and I don't think Rush is giving them political advice that will win the argument.
Then we could tell who really wants higher taxes and higher gov't spending.
