Republican Rep. Tony Gonzales narrowly won his primary against a gun-rights activist in Texas, avoiding a runoff that could have unseated him as a U.S. House incumbent.
State House Speaker Dade Phelan also narrowly defeated a challenger backed by Donald Trump, showing the influence of hard-line conservatives in Texas politics.
Both victories were by razor-thin margins, signaling a wave of discontent among the Republican base in the state.
