Georgia Gov. Brian Kemp, who drew Donald Trump's wrath for refusing to act on his false allegations of a stolen election, will face a prominent challenger for the 2022 Republican primary for governor: Former Sen. David Perdue.

Late Sunday, a website and text updates launched for a Perdue governor's campaign, proclaiming him "a bold conservative to unite Georgia," and inviting people to "join our team to stop Stacey Abrams," the likely Democratic nominee.

On Monday, Perdue made it official with a video message launching his candidacy, calling himself the only candidate who can "make sure Stacey Abrams is never governor of Georgia."

Perdue, the one-term Senator who lost re-election in a runoff race earlier this year to Democrat Jon Ossoff, cast himself as a uniter who can bridge the gap fracturing Republicans in the state.

Perdue blamed Kemp and Georgia's Republican Secretary of State Brad Raffensperger – who similarly rebuffed Trump's baseless claims of election fraud – for the schism in the party.

"Look, I like Brian," Kemp said with a smile in the video. "This isn't personal. It's simple: He has failed all of us and cannot win in November."

"Instead of protecting our elections, he caved to Abrams and cost us two Senate seats, the Senate majority and gave Joe Biden free reign," Kemp said, seemingly in a blatant attempt to blame voter fraud on the reason why Democrats Ossoff and Rev. Raphael Warnock won their Senate runoff races in January. (There is no evidence of widespread voter fraud in Georgia's elections, nor was there any evidence of any widespread voter fraud nationwide in the 2020 election.)

”Think about how different it would be today if Kemp had fought Abrams first instead of fighting Trump,” Perdue continued. “Kemp caved before the election and the country is paying the price today. It’s time for a change. If our governor was ever going to fight for us, wouldn’t he have done it already?"

News of his entry into the race was first reported by POLITICO on Sunday.

Kemp has been encouraged publicly by the former president and has been flirting with running for governor for months. Supporters of the 71-year-old former senator say they believe while Kemp can't beat Abrams, Perdue can emerge victorious.

In a statement Monday, Trump praised Perdue and slammed Kemp, but stopped short of offering a full-throated endorsement in the race.

"David was a great Senator, and he truly loves his state and his country," Trump wrote.

"This will be very interesting, and I can’t imagine that Brian Kemp, who has hurt election integrity in Georgia so badly, can do well at the ballot box," Trump said before making unfounded allegations of potential voter fraud, suggesting that the incumbent could only win in a "rigged" election.

"He cost us two Senate Seats and a Presidential vicotry in the Great State of Georgia," Trump falsely claimed.

"Perdue can bring together the Trump base and those Republicans, independents, and moderate Democrats who will find Abrams too radical," former U.S. House Speaker Newt Gingrich wrote on Nov. 12. "Perdue is the one candidate who can defeat Abrams."

But Kemp is promising an all-out brawl as he tries to win a second term, with Kemp spokesperson Cody Hall saying Perdue is running only to "soothe his own bruised ego" over his loss to Ossoff.

Hall branded Perdue "the man who lost Republicans the United States Senate."

As recently as June, Perdue was supporting Kemp, introducing him at the state Republican Party convention. Kemp said last week that he hoped Perdue "was a man of his word" when it came to that support.

Perdue's entry could drag Kemp to the right as he vies for primary support. Kemp had hoped to use Abrams' entry into the governor's race Wednesday to rally Republicans to his side, but Trump then issued a statement claiming that his strongest supporters would never vote for Kemp. 

Trump has repeatedly assailed Kemp, saying the governor didn't do enough to overturn President Joe Biden's electoral victory in Georgia. 

"The MAGA base will just not vote for him after what he did with respect to election integrity and two horribly run elections, for President and then two Senate seats," Trump said in a recent statement. "But some good Republican will run, and some good Republican will get my endorsement, and some good Republican will WIN!"

Trump's political action committee claimed earlier that Perdue could beat Kemp in a Republican primary if he had Trump's endorsement. At a Sept. 25 rally in Perry, Georgia, Trump pointed out Perdue among a clutch of Republican leaders.

"Are you running for governor, David?" Trump asked. "Did I hear he's running?"

Some Republicans fear a bitter Perdue-Kemp primary will set the stage for an Abrams victory. Republican state Sen. Chuck Hufstetler of Rome wrote in a tweet that Perdue's entry is "Good news for Stacey Abrams. Bad news for Republicans."

Born in Macon, Perdue was a business consultant, then an executive at companies shifting clothing production to Asia. He became CEO of Reebok, textile firm PillowTex and discount retailer Dollar General. The cousin of Sonny Perdue, a former governor and U.S. agriculture secretary, David Perdue was elected to the Senate in 2014, beating Democrat Michelle Nunn.

Besides Trump's displeasure with Kemp, it's unclear what Perdue's platform will be. In an interview last month with Gainesville radio station WDUN-AM, he talked about education, and contrasted the Trump economy to Biden's "maniacal spending." 

But he seemed to circle back to hard feelings over Trump's electoral loss, saying Biden won in a "questioned election." In fact, courts and state election officials across the country found no grounds to question the validity of Biden's victory.

"We have a divided party in Georgia right now," Perdue said. "Forget about me, it's divided." He said "a lot of people feel like that the people in power haven't fought for them, and caved in to a lot of things back in 2020 that didn't have to be done."

News reports indicated Perdue could announce his primary challenge as early as Monday.

There is already a slate of Trump-backed candidates in Georgia Republican primaries, including Herschel Walker running for U.S. Senate, state Sen. Burt Jones running for lieutenant governor and U.S. Rep. Jody Hice running for secretary of state.

Other Republicans have already been trying to challenge Kemp, including former Democrat Vernon Jones and GOP activist Kandiss Taylor. Jones has courted a Trump endorsement and on Sunday claimed Kemp and Perdue are "two peas in a pod."

Abrams has no declared opponents on the Democratic side. Her narrow loss to Kemp in 2018 vaulted her to national fame as a voting rights activist and leader of her party.

"While David Perdue and Brian Kemp fight each other, Stacey Abrams will be fighting for the people of Georgia," Abrams top aide Lauren Groh-Wargo wrote on Twitter.

Emory University political science professor Andra Gillespie said it's unclear if a Kemp-Perdue primary would be "demobilizing or demoralizing in a general election" for Republican voters, with some staying home.

 The national environment in 2022 appears likely to be strong for the GOP, and Gillespie said "Republican voters are going to go vote for a Republican candidate, and they'll put whatever differences they have aside to support that Republican candidate."
