Democrat-turned-Republican Vernon Jones was further beaten in the 10th District of east Atlanta by trucking company owner Mike Collins.

Despite Tuesday's losses, Trump took a win in Alabama after attorney and businesswoman Katie Britt defeated Rep. Mo Brooks for the Senate nomination, who saw his survey numbers fall after the former president withdrew his endorsement.

McCormick was praised by Texas Sen. Ted Cruz and a handful of Georgia congressional members, including Reps. Jody Hice, Marjorie Taylor Greene, and Buddy Carter, in this latest race.
The runoff between McCormick and Evans centered on their Republican ideals, with both candidates claiming that the other was not conservative enough.
His opponent was endorsed by Trump. The former president held a tele-rally Monday night, calling on his followers to vote for Evans.
"Jake has been a fearless defender of our Constitution," Trump announced throughout the event.
"Jake risked his entire career — he took a big risk, his entire career actually — to fight for election integrity for Pennsylvania's illegal and unconstitutional election law changes all the way to the United States Supreme Court."
Trump called Evans a "MAGA warrior" and claimed that the Georgia lawyer would be elected to office and do an "incredible job."
