Texas GOP voters decide Senate runoff that could reshape party and Senate control

Texas Republicans are voting in a primary runoff between Senator John Cornyn and Attorney General Ken Paxton, a race that could determine the future of the GOP and control of the U.S. Senate.

- The runoff is the most expensive primary in history, with over $100 million spent. - Paxton, endorsed by Trump, accuses Cornyn of betraying the party; Cornyn warns a Paxton nomination could lead to a Democratic win.

- The race reflects a national ideological battle between traditional conservatives and the MAGA populist wing. - Paxton has legal baggage but is seen as a fighter; Cornyn emphasizes his high Trump voting record.

The outcome will signal whether the Texas GOP moves toward populism or remains with establishment conservatism, with potential national implications.
