It was Trump who publicly urged Walker to run shortly after his own election defeat, saying his old friend would be “unstoppable.” And it was Trump last week who said on a conservative radio show that Walker was readying to run.

“He told me he’s going to, and I think he will,” Trump said. “I had dinner with him a week ago. He’s a great guy. He’s a patriot. He’s a very loyal person.”

Walker has only confirmed he’s still considering a bid, but his likely candidacy is an open secret in Georgia’s political world. In recent weeks, he’s lined up advisers and started building the foundation of a campaign. Senior Republicans who once heard zip from Walker now see him as a surefire contender.

He would be the rare celebrity candidate in Georgia, a state where famous sports figures and media personalities have mainly steered clear of politics. (For example, Walker’s famed former coach, Vince Dooley, passed on a run for governor in the late 1980s, saying his heart wasn’t in it.)

His name recognition from his career at the University of Georgia, where he won the Heisman Trophy and led the team to a national championship, would be one of his greatest assets. So would his potential to help broaden the party’s appeal as a Black conservative in a matchup against Warnock, the first African American senator in the state’s history.

But Walker’s potential candidacy triggers more questions than a conventional candidate would face, some more freighted than others. His history of mental illness, including violent episodes he’s publicly addressed, will be invoked by rivals from both sides of the party divide.

And he must move to Georgia from Texas, where he’s lived most of his adult life, to woo a conservative base that knows him for his athletic legend — and not for his ability to connect with voters, his grasp of policy ideals or his prowess on the campaign trail.

“Herschel Walker will need to come back to Georgia and campaign. He will need to show that he is a conservative,” Doug Collins, a former Republican congressman and 2020 Senate candidate, said on his radio show.

“I have never heard Herschel Walker’s position on pro-life. I haven’t,” Collins said. “I’ve never heard his position on gun control. I’ve never heard his position on a lot of these issues that are conservative issues.”

‘The long haul’

That Republicans are waiting anxiously for an iconic football star to kick off his campaign while veteran politicians wait on the sidelines is a symbol of Trump’s enduring influence in state Republican politics.

The former president has a long relationship with Walker dating to his stint on a United States Football League team that Trump owned. Walker was a key surrogate for Trump during his 2016 campaign and spoke on his behalf at last year’s Republican National Convention.

Even the hint of a Trump endorsement in the race has kept well-known Georgia figures out of the race. For months, the only two GOP contenders were military veterans Kelvin King and Latham Saddler, both conservatives with impressive backgrounds but low public profiles.

Collins decided early that he wouldn’t try to wage a rematch against Warnock following a third-place finish in last year’s special election. U.S. Rep. Buddy Carter has said he’ll wait for Walker to make up his mind. And former U.S. Sen. Kelly Loeffler is also holding pat for now.

The biggest exception is Agriculture Commissioner Gary Black, who launched his campaign at the Georgia GOP convention in June — a gathering of thousands of activists that Walker skipped — and has since built out a grassroots network in every Georgia county.

“I’m in this race to win the primary and the general election,” Black said of the possibility of a Walker run. “I’m in it for the long haul.”

Democrats, meanwhile, are so far avoiding a direct attack on the football icon, instead focusing on policies that helped Warnock and Jon Ossoff score a sweep in January’s Senate runoffs.

“Whether it’s Herschel Walker, Kelly Loeffler or any of the other candidates, their priority is doing whatever it takes to come out ahead in this chaotic primary,” said Dan Gottlieb, an adviser with the Democratic Party of Georgia, “not helping Georgia families recover from this pandemic, creating new job opportunities or expanding access to quality, affordable health care.”

A big unknown

One of the biggest unknowns is how Walker would confront his history of mental illness — and how his rivals will address it.

Walker says he suffers from dissociative identity disorder, which he traces to an isolated childhood in rural east Georgia where his speech impediment made him a frequent target for bullies. Voices in his head that once calmed him steadily transformed into distinct identities that shaped his actions.

He outlines his mental illness in vivid detail in his 2008 book, “Breaking Free: My Life With Dissociative Identity Disorder,” writing candidly about his infidelity and suicidal thoughts.

His former wife, Cindy Grossman, has also spoken publicly about her then-husband’s threatening behavior and said that he once put a gun to her head during a violent rage that Walker later said he didn’t remember.

His mental illness seems certain to be discussed on the campaign trail, if not directly by other candidates, then by their allies. But veteran politicians also say his forthright battle with the illness could become an inspiring part of his personal story.

“All candidates face challenges, and you can get by as long as you have a good explanation,” said former U.S. Rep. Jack Kingston, who ran for the Senate in 2014.

That hasn’t settled Republican concerns. Some privately complained that Walker wouldn’t return their calls or griped that the drawn-out process would hurt the party in the long run, particularly if he has second thoughts and decides against announcing.

Others worry his first day of the campaign would be his best — and that it would all go downhill if he doesn’t chart his strategy properly.

“He needs to show conservative policy positions early, prove he can look forward and take it to Warnock and build a professional operation,” said Cole Muzio, who runs the conservative Frontline Policy Council.

“There’s no doubt that the impact of his announcement will be massive,” Muzio said. “But after taking significant time to evaluate the race, he will need to demonstrate he’s ready for the nation’s most important Senate contest — one we shouldn’t and can’t afford to lose.”

Erick Erickson, a prominent conservative commentator, said he’s more concerned about lasting damage to Walker’s campaign from campaign staffers than the critiques of his past or his policy stances.

“His day-to-day team is going to matter, and because there’s been buzz for some time in Trump circles, I worry a rich man from out of state with fame is going to be circled by grifters like vultures do to roadkill,” Erickson said.

Walker, meanwhile, is keeping mostly mum. He tweeted a cryptic video in June featuring a Georgia license plate that suggested he was moving to the state. And in a statement shortly after Trump’s radio interview, Walker said he’s still not ready to declare himself a candidate.

“Georgia is my home — I love Georgia, and I love this country,” Walker said in the statement. “And I believe we need fighters to step forward and help save both. Know this much: If I run, I’ll be all-in, and we will do whatever it takes to win for Georgia.”
