Cornyn faces a challenge from Texas Attorney General Ken Paxton and U.S. Rep. Wesley Hunt.
WASHINGTON — Republican Texas voters are heading to the polls to cast their ballots in one the most-watched races in the country: the primary for U.S. Senate.
Longtime incumbent U.S. Sen. John Cornyn is seeking a fifth term. Seven other Republicans are challenging him, including Texas Attorney General Ken Paxton and Congressman Wesley Hunt of Houston.
The race has been a tight, contentious one since Paxton announced his intention to run for Senate last April and Hunt joined the race in October. Cornyn and Paxton have consistently been neck-and-neck in the polls, with most too close to call for one candidate or the other.
Live results for the Republican primary race for U.S. Senate will be posted here as the polls close at 7 p.m.
The winner of the Republican primary will face the winner of the Democratic primary in November. That will either be Congresswoman Jasmine Crockett, State Rep. James Talarico or Ahmed R. Hassan.
If either primary goes to a runoff, that election will be held on May 26. The general election is scheduled for Nov. 3.
