Is there a Hillary Tax Return Gate Coming?

Tax Return-Gate?

Why won't Hillary Clinton release her tax returns "until the is the nominee"?

Hillary claims she has been "fully vetted".
Hillary claims there will be no more surprises.

Yet Hillary Clinton has thus far refused to release her tax returns.
She says she will do when she is the Democratic nominee for President.

What does she have to hide by releasing them now?

Obama released his returns last April, 2007.

What is Hillary afraid will be found in her returns?
Something that will help her lose the nomination?

Previous Democratic campaigners released their returns before they were the nominee.

According to the Washington Post,
John Kerry released his returns in December 2003, which was well before winning the nomination.
Al Gore's returns, were already public when he ran.
Other potential nominees like Dean, Clark, Kucinich, Gephardt, and Lieberman all released their returns early.

In 1992, Bill Clinton made his tax returns public before he was the nominee. Sort of.

BUT-- He didn't release his 1978-79 returns.

These were a bit of a smoking gun because they showed Hillary had made a 10,000% cattle-futures profit.

So, now why is it that Hillary isn't releasing her returns?

Hillary's returns could have something that could be negative to her campaign in them. If she releases her returns now, it would give Democratic voters the chance to judge her on what's in her returns, and vote accordingly. But if she waits until after she becomes the nominee, she figures she will still get the Democratic vote even if there are negatives. As a Democrat calling for change, people may not vote Hillary if they see the same old issues popping up in her tax returns again. Democratic primary voters and the Super Delegates might not like what they find, and vote Obama.

If she has nothing to hide, what is she hiding?
