Excellent question, but it starts with a false premise: we can't trust Republicans to stop crap.
They've not stopped Fast and Furious.
They've not stopped the NSA's domestic espionage programs.
They've not stopped the IRS's political targeting.
They've not stopped the blatant ignoring of the border.
So, then, why should we believe that they will stop this?
Don’t ask me. Ask our GOPj friend.
