The Dems know this, but since most of Bush's WH doesn't leak, they can't get a handle on where they are looking. Thus you get the wild attacks on Pitt.
Take a step back and look at the bigger picture with a timeline tossed in. Much of the current fraud being investigated goes back to impeachment times. Why were we told we couldn't get rid of Clinton. Right, it would damage the economy. Cook the books and when Algore gets elected, we will put them back in order and no one would be the wiser.
Two problems... Bush won and 911 hit. Economy turns really south and the cover has been blown.
Trust me, between now and election day, expect indictments against major players in the Democrat Party.
One well-placed Justice probe around, say, October 1 ought to do the trick.
