No. He needs to get his butt out so the GOP guv can pick someone NOW.
Suppose the GOP guv picks a RINO or another open-borders type to "replace" him? Then we're stuck with an even worse incumbent. We have primary elections in this country for a reason. Idaho Republican voters have the right to make that choice. There's no reason to create an artificial vacancy when none exists. The Guv can pick whoever he wants provided Craig falls into a coma, dies or is sent to prison. Until then, screw him.
The idea that Craig should resign when a PROVEN crook like William Jefferson is allowed to serve out HIS term is the biggest joke I've ever heard. Craig should call the Dems on their hypocrisy and announce he will resign the moment Jefferson does. I won't hold my breathe waiting for them to take him on it.
What next, we make every GOP Senator suspected of having perverted sex lives resign as well?
