Georgia Republicans are expected to reject Donald Trump’s campaign to oust governor Brian Kemp.
However, polls for the primary election show they are likely to back a former football star he has endorsed in their US Senate primary.
The former president has backed primary challenges to Mr Kemp and Georgia secretary of state Brad Raffens-perger for rejecting his attempts to overturn his 2020 election defeat, which he falsely claims was the result of widespread fraud.
While polls show Mr Kemp with a strong lead and Mr Raffensperger locked in a close race, another Trump endorsee, former football great Herschel Walker, looks set to easily snag the Republican nomination to run for the US Senate.
Some party leaders worry his controversial past could doom his chances in the November mid-term elections.
Republicans are expected to win a majority in the US House of Representatives on November 8, but polls suggest Democrats have a better chance of holding on to their slim majority in the Senate.
The loss of either chamber would bring President Joe Biden’s legislative agenda to a halt and give Republicans the power to launch distracting and potentially politically damaging investigations.
Mr Trump has made more than 190 endorsements since leaving office, most of which are for incumbent Republicans who face no serious primary opposition.
While propelling some candidates in close contests to victory, his endorsement has at times fallen short. Mr Trump’s pick for Nebraska governor, who was accused of groping multiple women, lost his primary race. His nominee for US Senate in Pennsylvania is in a race too close to call a week after voting.
Opinion polls show Georgia incumbent Mr Kemp well above the 50pc threshold needed to win the nomination outright and avoid a run-off against Mr Trump’s hand-picked challenger, former US senator David Perdue, who has repeated Mr Trump’s falsehoods about losing Georgia due to voter fraud.
Mike Pence, who was Mr Trump’s vice-president, urged voters not to dwell on the past when he campaigned for Mr Kemp on Monday, speaking at a rally in Kennesaw, Georgia.
“Elections are about the future. There are those who want to make this election about the past,” Mr Pence said.
“When you say yes to Governor Brian Kemp tomorrow, you will send a deafening message all across America that the Republican Party is the party of the future.”
