Double standard?

Following a sting operation by the Federal Bureau of Investigation, several members and former members of the Tennessee General Assembly have been indicted for accepting bribes.
They were supposedly given money to pass certain legislation from which a particular company would be able to profit.
One problem: The company didn't really exist; it was a front by the FBI.
Still, several Democrats and one Republican are accused of having taken the bait.
A few days ago, a vocal "moral leader" of the Tennessee Republicans called for the indicted Republican to resign or be thrown out of the legislature.
Times cartoonist Bruce Plante, Pulitzer Prize winner, immediately penned a vitriolic cartoon denouncing the "moralist" for not even giving the accused a fair trial before hanging him, for forgetting that even a politician is innocent until proven guilty.
On Tuesday, 12 July 2005, the same Bruce Plante, Pulitzer Prize winner, drew a cartoon of a man and woman staring at a poster, "Slime-Man" apparently a movie "starring Karl Rove."
The woman asks, "What are his super powers?"
The man answers, "Revealing the secret identity of heroes and sliming his way out of it."
On Wednesday, the Times editorial is headlined, "Karl Rove must go."
Last I heard, as of Wednesday afternoon, Karl Rove has not been proved guilty of anything, except being a Republican.
Granted that's a pretty bad sin, but it's not yet a crime.
Except, apparently, to cartoonist Bruce Plante, Pulitzer Prize winner, and whichever vitriolist of the Times editorial page wrote the editorial.
Double standard? or no standard?
