The impact of Georgia's primary elections on Tuesday will reverberate far beyond state lines, as key races up and down the ballot test former President Donald Trump's political power and set the table for a showdown over which party controls Congress.

More than a dozen candidates in the Peach State primaries have been endorsed by Trump.

Georgia's Gov. Brian Kemp and Secretary of State Brad Raffensperger both resisted pressure from Trump to overturn the election of Joe Biden.

The Trump-backed challengers in both of those GOP primaries echoed the former president's false claims that the 2020 presidential election results were rigged.

Trump has thrown his support behind Herschel Walker, a former running back who is expected to advance to the general election for Senate against Raphael. The election of Warnock over Republican Kelly loeffler in a pivotal 2021 runoff election helped Democrats seize a razor-thin majority in the Senate.

Trump endorsed Rep. Marjorie Taylor-Greene, who has made her a villain among Democrats because of her extreme conspiracy theories.

The key question for some of today's races is whether a candidate can avoid a second election if they get more than 50% of the vote.

Georgia's primaries arrive as Republicans hope to wrest control of the House and Senate from the Democrats in the fall. The president's party tends to lose in the mid-term elections, and the lead-up to the primaries has been marked by high inflation and low approval ratings for Biden.

In Alabama, Arkansas, Texas and Minnesota, the dynamic is the same.

The daughter of an ex-governor is also a former press secretary for Trump. Huckabee is expected to win the GOP gubernatorial primary. The open Senate seat in Alabama is being fought for by GOP Rep. MoBrooks after Trump withdrew his endorsement.

Georgia's primary elections are open on Tuesday. The time is from 7 to 7 p.m. Time.

Here is what to watch.

Perdue lost the Senate race to Jon Ossoff last year, and is now trying to win the governor's office in Georgia.

Perdue, who is endorsed by Trump and has been campaigning in part on spreading the former president's false claims about the 2020 presidential election, appears to be falling behind Kemp.

Recent polls show Kemp with a double-digit lead over Perdue. The polls that were conducted after the ads attacking Kemp were aired were part of the gap.

Kemp has cultivated a reputation as a conservative after signing a highly restrictive abortion law. He has been endorsed by former Vice President Mike Pence, whom Trump has attacked over his refusal to reject Electoral College votes.

Kemp has been slammed by Trump as a very weak governor who has failed Georgia.

The president said in a statement that Perdue can't win because of the "MAGA base" which will never vote for him.

According to sources close to Trump, he had no plans to campaign in person for Perdue as of last week.

The progressive Democrat who narrowly lost to Kemp in the governor's race will face the Republican who advances to the general election.

When he ran for governor, Kemp refused to step down as Georgia's secretary of state, despite concerns about his involvement in an election that his office was in charge of overseeing. In the wake of that loss, she said the race was unfair.

In the GOP primary for Georgia's top elections officer, Trump has backed Rep. Jody Hice, one of the dozens of congressional Republicans who voted to challenge Electoral College results.

The number that Trump believed was required to overturn Biden's victory in Georgia was 11,780.

The phone call was leaked to the media. After the call, Trump wrote that Raffensperger had no clue.

The phone call is being eyed in a criminal investigation into Trump's efforts to overturn the election results.

Hice supported a legal effort to overturn election results. He has launched an array of attacks against Raffensperger's handling of the 2020 election, some of which fact-checkers have labeled false.

Walker is expected to easily win the Republican nomination for Senate in Tuesday's primary.

According to an average of recent surveys, Walker is more than 50 percentage points ahead of his closest rival.

Walker is likely to face stronger opposition if he wins the November election.

The politically unseasoned athlete, who has skipped debates and faced accusations of avoiding non-friendly press, can expect to face more heat in the general, possibly about his reported history of alleged domestic abuse and making exaggerating claims about his business.

According to RealClearPolitics, the candidates are virtually tied in early polls.

A number of Trump loyalists have challenged the results of the 2020 election. The congressman caused outrage last year when he claimed that the pro-Trump mob that swarmed the Capitol looked more like a tourist visit than a riot.

In Georgia, the 14th congressional district is the most watched House race. The Democrat-led House stripped her of her committee assignments last year for peddling a wide array of extreme views and conspiracy theories before she was elected.

According to media outlets, in the days after the Capitol riot, the then White House chief of staff MarkMeadows received a text from Greene urging him to talk to Trump about martial law.

An election-reform group had filed a lawsuit to try and kick her out of the primary race because of her actions related to the Capitol riot. Secretary of State Raffensperger ruled earlier this month that the reelection campaign can continue despite the judge's ruling against it.

Georgia's primaries mark a test of whether Trump still holds the same sway over the direction of the GOP 15 months after he left the White House.

Trump's endorsement record in the current primary cycle is seen as a key measure of his influence by some political watchers. Trump's win-loss record may not tell the whole story.

Most of Trump's endorsees have won their primaries, but some candidates ran with little or no opposition. Pennsylvania's Republican gubernatorial nominee, Doug Mastriano, received Trump's endorsement before the election.

In Georgia, Trump endorsed three Republican House members just days before the election.

Trump's record is mixed in high-profile races. Some of Trump's endorsements appeared to make a difference, such as his backing of Alex Mooney, a West Virginia Republican who won his House primary. J.D. Vance won the Ohio Republican Senate primary after winning Trump's support.

The other Trump-endorsed candidates lost a lot. Even after Trump held a rally in the state and defended Charles Herbster against recent sexual-misconduct allegations, he failed to win the GOP nomination for the Nebraska governor's race. There were accusations from multiple women.

Even though he had an endorsement from Trump, Rep. Madison Cawthorn lost his primary in North Carolina. Cawthorn, the youngest member of Congress, was dragged down by a laundry list of scandals that had alienated him from many of his fellow congressional Republicans.

McGeachin, Idaho's lieutenant governor, lost her challenge of the state's incumbent Republican Gov. Brad Little by a wide margin. Unlike Kemp and other incumbent Republicans being challenged by Trump's picks, Little had not publicly stirred Trump's anger prior to his endorsement of McGeachin.
