Apparently, Senator Obama called on Senator Clinton to release her income tax returns, saying he had released his in an effort to be transparent. Update: It looks like he stopped short of asking them to disclose their returns. The abcnews link has a video link, but that keeps directing to a McCain video. Hmph.
The Clinton campaign's response: "When will Senator Obama release the complete details of his relationship with Tony Rezko?" That reminds me of the "Nazi" name-calling in an argument - the moment one party says the opposition is a Nazi, the first party has lost.
Hell, even President George W Bush released his tax returns. So did Senator John Kerry during their 2004 election. So does this mean Senator Clinton is less-transparent than W? Yikes.
I've also read that the story about the Clinton campaign running short of cash may have been a stunt. Though it looks like her staffers offered to go without pay, but the $4 million the campaign raised through Wednesday saved them - for now.
