Polls in Texas close at 7 p.m. local time for the primary, but starting at 7:15 p.m., there will be a caucus, so all voting will not conclude until 9. Because parts of western Texas are in the mountain time zone, that translates into 11 p.m. eastern. Given the closelessness of the race, it will probably take a long time to project a winner. In other words, expect a late night/early morning ordeal.
