Quoting your entry "In 2000, Clinton was still first lady, and vying for an open Senate seat in New York with then-Congressman Rick Lazio. Lazio entered the race in May of 2000..."
So...April 15th (which last I looked is filing day unless it falls on a Sunday or federal holiday in which case you typically get to file a day later) is before May. And Clinton's current return is due on April 15th. And in the meantime, Hillary has to file public disclosures of income because she holds a seat in the US Senate.
Does anyone think there will be some sort of smoking gun in Hillary Clinton's tax returns? Really? And if there is, wouldn't the recent pledge to release these returns around April 15th when the most current return is due amount to political suicide? That would give opponents a week to comb through her tax filing with a fine tooth come, devoting as much staff as it took to do so, and hammer her relentlessly in the week before the Pennsylvania primary.
On this "issue", there seems to be no there, there.
