Why doesn't Romney release his tax returns for 8 years?

Rush was so upset today, it was kind of funny. He was really dissing Obama, calling him an idiot, etc. I wouldn't call Obama an idiot, really, just someone who is not really good for the country...

Anyway, Romney is being criticized for not releasing more of his tax returns. Rush rejoins - why don't you share your college transcripts?

Well - although I certainly would like to see Obama's college transcripts, that's not the issue. If Obama has released 5 or 10 years of income tax returns, why shouldn't Romney? If he's got nothing to be ashamed of - release them!

(And yeah, if Obama isn't ashamed of his college grades, why doesn't he release them?)
