I early voted on Friday last week (the last day in which to do so here in Houston Texas). It was PACKED like I have never seen it. There were approx 250-300 people waiting to vote. I stood in line for 2 hours before I got to vote. No one was leaving the lines either. Everyone stayed to vote!
Note, this is an overwhelmingly Republican county—but still! I was so glad to hear turnout sounds high!
You may could avoid the lines if you had voted early and been one of the almost 90,000 that voted early in Collin County this election.
