Gov. Brian Kemp's decision not to run has some Republicans concerned that Rep. Marjorie Taylor Greene might decide to jump in and, in their view, jeopardize the GOP's chances.

Georgia Gov. Brian Kemp is passing on a bid for US Senate, delivering a major blow to GOP leaders who have spent months trying to lure him into vying for one of their biggest targets of the midterms.

Republicans see Georgia as their top pickup opportunity and saw Kemp as the strongest candidate to challenge Democratic Sen. Jon Ossoff.
