John Cassidy, The New Yorker: “With even prominent Republicans saying that his current stance is unsustainable, the obvious question to ask is: Why is the Mittster being so obstinate? He surely isn’t standing on principle, for what principle would that be? The notion that very rich men running for President shouldn’t have to disclose as much information about their personal finances as less wealthy candidates? The principle that if your father also ran for President, and released twelve years of tax returns, then you can release just two and claim the family average is a respectable seven years? No. It’s only fair to assume that Mitt is doing what he always does: acting on the basis of a careful cost-benefit analysis.”
