Texas’ raucous primary runoffs end today. Here’s what to watch.

Three runoff elections in Texas are of particular interest. Top left: Texas Attorney General Ken Paxton, who is challenging incumbent U.S. Sen. John Cornyn (top right). Middle left: U.S. Rep. Chip Roy, vying for state attorney general against state Sen. Mayes Middleton (middle right). Bottom left: incumbent Railroad Commissioner Jim Wright, who faces challenger Bo French (bottom right).

John Cornyn is trying to fend off Ken Paxton. Both parties are picking attorney general nominees. And an oil and gas regulatory race has become uncharacteristically costly.
