I think she's right. We got there at 6:45am and there were at least 30 ahead of us. By the time we voted and walked out, the line was longer, and all the booths were filled.
So, it looks like a heavy turnout in Oklahoma, at least in our small corner of it.
OBTW, in my exit polling, Bush-Cheney-Coburn got 100% of the vote (sample size = 2, my wife and me)
My exit poll was similar -- 2 Bush, 2 Bataglia (Dump Betty McCollum).
