Former Clintonite, Michael Zeldin, writes of the problem with the Hillary brand. It's been tarnished by her exaggerations, misstatements and evasions.

She claims she would the better candidate against McCain because she has been fully "vetted" but she hasn't. Zeldin writes: "... the recently released tax returns appear to undermine this argument as well."

"Specifically, these returns demonstrate the former President Clinton made tens of millions of dollars on the speaking circuit and by helping to broker business deals or make introductions around the world. This is his prerogative as a private citizen. What the returns do not tell us, however, is who paid for these speeches; who his clients were/are; whether he can unwind his business relationships (he is being sued by one of his clients for fraud in state court in California); what conflicts of interest or appearances of conflict reside in his seven-year, private-sector career."

The Clintons also refuse the donor list to the Clinton Library. To be fair, George W. Bush has said he's not sure whether he'd release the donor list to his future presidential library.

It could be a problem when Laura Bush runs for president.
