Below is the final unofficial count for State Representative District 146. Sixty votes short of averting a run-off. I am sure that my mailbox will be full for a couple of months as my wife and I always vote. I supported and recommended Lauren Simmons in the primary.
Note that the U of H poll was way off in the state rep 146 race. They were also way off on most of the other races, but they only remembered the Teare v Ogg race, as they got that right.
Texas House District 146: 40% of likely Democratic primary voters plan to vote for State Rep. Shawn Thierry for Texas House District 146, while 16% support Lauren Ashley Simmons and 4% support Ashton Woods. 40% of likely Democratic primary voters remain unsure. Source
Constable Precinct 5 also has a run-off. I expected Jerry Rodriguez to be there but Jerome Moore surprised me. I will be looking into that race to see who I will be voting for.
Harris County Tax Assessor another run-off. I expected Annette Ramirez to be in a run-off.
