I’m wondering if Clinton has been playing rope-a-dope with Obama, getting him to say this:
“In the face of her unwillingness to release her tax returns, Hillary Clinton has made the false case in this campaign that she is more electable because she has been fully vetted,” the memo stated. “When it comes to her personal finances, Senator Clinton’s refusal to release her taxes returns denies the media and the American people the opportunity to even begin that process.”
So that her camp can promise a release date (tax day of course 🙂 and then say something like this:

“Over 20 years of the Clintons’ tax returns are in the public domain,” he said. “Their tax returns since they left the White House will be made available on or around April 15. This information will be in addition to 15 years of uninterrupted public financial disclosure reports.”
“Instead of making false attacks, we urge Senator Obama to release all relevant financial and other information related to indicted political fixer Tony Rezko,” Wolfson also said.

And when she does release it there will be nothing there and she’ll say, “See? I said that I’ve been fully vetted and have nothing to hide, what about Obama?”
