He will still vote for a Republican leader of the Senate instead of Harry.
If you can't count on them doing that, then you don't vote for them.
I think Allen will vote with the Republicans, and we know where he lives. He will vote as Conservative as we can convince him of what the Conservative position is.
Now, to get a prybar and separate him from McDonnell and his cronies. They're not getting him back into the Senate ~ but they'll glom onto him once that happens.
