I voted a straight Democratic ticket today, and moreover, I voted against Republican candidates in several judicial elections that didn't have a Democratic candidate, by voting for the Libertarian candidate.
That being said, I want to note for the record that my precinct is 0498, Harris County, Houston, which is located in the Northwest Church of Christ, just west of Bingle on Tidwell. The police are running a speed trap on Tidwell less than a block west of the polling location. There were two officers and two squad cars just off Tidwell on the side street, and they were aiming a radar gun down Tidwell to tag drivers headed in the direction of the polling place. (I.e., on the south side of Tidwell, targeting eastbound drivers.)
I've already reported this to 1-866-OUR-VOTE, who'll presumably know what to do next.
