ATLANTA (AP) — Georgia takes center stage in Tuesday’s primary elections as Gov. Brian Kemp and Secretary of State Brad Raffensperger try to fight back challengers endorsed by Donald Trump. Congresswoman Marjorie Taylor Greene of Georgia is testing Republican voters’ tolerance for controversy in her primary. In Alabama, three Republicans are in a tight race for the nomination to replace retiring U.S. Sen. Richard Shelby. In Arkansas, former White House press secretary Sarah Sanders is a front-runner for the Republican nomination for governor. In two Texas runoffs, Attorney General Ken Paxton is trying to hold off Land Commissioner George P. Bush, while congressman Henry Cuellar is facing a progressive challenger.
