Sorry for the short diary. I've stumbled upon a question that makes me curious. What's the deal with the date April 15? Hillary Clinton has announced the she will release her taxes on that date. Now, McCain is announcing that he will release his medical reports on April 15. So what's the deal? Is there a deadline on the 15th for which candidates have to release their records? Is there a fundraising deadline? Are they trying to cover each other -- working together to mitigate their negatives? Should we expect negative news from both of their records?
