FORT WORTH, Texas (AP) — Tea party activists seized control of the Texas Republican Convention on Saturday, winning a harder line on immigration in the official party platform and lifting firebrand U.S. Sen. Ted Cruz to an easy victory in a 2016 presidential straw poll.

Following hours of often contentious debate and an especially raucous vote, the roughly 7,000 delegates torpedoed platform language approved at their convention just two years ago endorsing a guest-worker program for people in the country illegally.
