Absolutely! She is, at the very least, going to vote as a democrat and most probably will make a huge, dramatic public announcement when she makes the official switch.
We have NOTHING TO LOSE by dumping the botch first and everything to gain:
1) It takes all the triumph out of her switcheroo and makes her the loser being dumped and
2) It sends a message to any other traitor that we are serious about being republicans.
Short term very small loss--if it's even a loss at all, long term win.
In a way, it would be kinda cool for the GOP to dump her before she quits.
But, it won’t happen.
Nor should it.
