Is Karl Rove a Big Fat Liar???
Well Duh!
When Ole Scooter goes on Trail, Snarl Rove will be called. So he has a bit of time between now and then to rehearse his next collection of distorted truths. (Good chance however, what with his bad memory and all, he will have forgot the details when he is called to testify!)

So he got himself some breathing space but more importantly, Snarl is around for the November deflections, I mean, Elections.
A Guy that spins Lies for a living would be so stupid as to allow himself to be indicted when the White House is nearly on it's knees seeking approval!!
