Things have slowed down quite a bit, but there's a steady trickle. It's actually nice for us, because then we have time to talk to (usually self-identified) Obama supporters, to explain the inexplicable -- i.e., why they MUST vote twice today. As Bill Clinton says, Texas is the only place in the country where you can vote twice without getting arrested.
Turnout in this very Republican area is running 2-to-1 for the Democrats (oh, forgot to mention there is a GOP primary going on as well!) That's a total turnaround from the traditional numbers. Hard to know, but I will not be surprised if this precinct goes 2-to-1 for Obama, many of whom say they will come back at 7 pm tonight to caucus.
