Texas primary runoffs: Election deniers favored in key GOP Senate and attorney general races

Texans are returning to the polls Tuesday to vote in several key statewide and congressional primary runoffs that will have major implications for voting rights and elections both in the state and nationally.

The tight contest between four-term incumbent Sen. John Cornyn and Trump-backed outgoing Texas Attorney General Ken Paxton for the GOP's U.S. Senate nomination will be the most closely watched of the night.

But Texas voters will also choose the Republican and Democratic nominees who could eventually succeed Paxton as attorney general later this year.
