It's far too early to say that Voinovitch is saying the wrong thing but doing the right thing, so we should give him a pass.
First of all, he is strengthening the Democrat propaganda machine and giving them bipartisan cover. Second, he is putting more pressure on his fellow RINOs to vote against Bolton. Third, he may still vote against Bolton on the floor of the Senate. It's not yet certain whether Bolton has enough votes for confirmation after all these dirty lies, and Voinovitch is still being extremely unhelpful.
As it was, I was awakened by a phone call and after answering it, clicked on the TV which happened to be on Fox News...I wasn't, at first, paying attention but the ears perked up as Voinovich droned on about what a bad, bad man that mean, ol' Bolton is...but got exceptionally outraged when after 15 minutes of sliming, Voinovich tried to mollify GOPers like me by saying he thought Bolton an honorable man who has given good service to the United States...hey, Voinovich, if he's a good man who's given good service, then you've got no beef and should vote to approve...its not your call, you piss-ant, to determine whom the President selects for Administration jobs...
