Romney has decided to release his tax returns. I think he always intended to. He wanted someone to make a BIG DEAL out of them and the release will be anticlimactic. Plus people kind of want a guy who knows his way around business and the economy right now. Class warfare in terms of the "fairness" of a guy who honestly made a lot of money in America so it is only "fair" that he give a bunch of it away to people who haven't made a lot of money in America may play well with Obama's core constituency, but it does not play well with middle America. And Obama's core constituency would never vote for Romney (or any Republican) any way.
