And yes, only a person who voted in the GOP primary can vote in the run-off. That's a hard fact. You've got it wrong according to the Red State analysis you linked:
If a person voted in the Democratic primary Tuesday, he or she cannot vote in the June 24 Republican runoff — and vice-versa. Obviously, the pool of Democrats who sat our their own primary but who will be sufficiently motivated to show up to vote in the GOP runoff is very small.
That is the pool we are talking about. And RedState's analysis is not necessarily well-reasoned. Childers won with 75% of the primary vote. That means the number of Democrats available to vote in the runoff may be substantial. Just their ability to turn out unionized bureaucrats may be enough.
I thought that's what I said, or rather, meant to say..sorry, my bad..at least I got you the correct information..hope that helps..
Also, don't forget the 3rd guy in the race...I suspect nearly all of his voters will come out for McDaniel.I read somewhere that the guy is a very successful realtor, so they assume that everyone who ever bought or sold a house through him, or he ever helped with a mortgage, voted for him..
