Rich man hurts only himself (and Republicans)

Mitt Romney's stubborn and politically stupid refusal to release his tax returns seems to be costing him a lot of political capital.  He was booed by Republicans at tonight's South Carolina debate.  And these are people who had just cheered Newt Gingrich's adultery!  Clearly the only reason Romney won't release them is he because he's embarrassed what they'll show.

The pressure to release them is only going to get worse and worse.  He's being a complete idiot for holding out.
