June 14 primaries key takeaways: Trump's political sway renewed, as South Carolina ousts one of his critics

As former President Donald Trump's presidential legacy is tested in Washington this week, with the Jan. 6 hearings dominating Capitol Hill, his political power -- and the sway of his election denying -- saw a renewed test in the midterm primaries in a handful of states. Voters took the polls in South Carolina, Nevada, Maine, North Dakota and Texas' 34th Congressional District Tuesday night, delivering historic turnout numbers and allowing voters to give Republicans who defied the former president a second chance at keeping their jobs, and some Democrats to lose theirs.

Here are some key takeaways from Tuesday's races:

Trump finally lands incumbent ouster

While Trump's had some success in backing candidates in open races, he's had major difficulty in knocking off incumbent members of his party who have challenged him in some way, putting aside the score of Trump-scorned Republicans who have decided to not seek reelection.

But finally, on Tuesday, Trump was able to handedly bump off one of the most vocal of that list, GOP Rep. Tom Rice of South Carolina, rendering him out of a job come November. Rice was one of 10 Republicans who voted for Trump's impeachment, a "conservative vote" he told ABC News' Jonathan Karl that he would make again in a heartbeat, even if it cost him his job. And lost his job he did, to MAGA-world challenger Russell Fry, who was quick to paint Rice as a traitor to his party. The demographic makeup of Rice's district, toward the northern border of the state where voters trend far more conservative, may have also contributed to the massive backlash against him, pushing folks toward Fry's direction.

Now, with newly-won swagger, Trump will undoubtedly charge on to try to defeat another Republican who supported impeachment, and maybe his biggest enemy yet, Wyoming Rep. Liz Cheney. The question remains: Can Trump's lightning -- and political luck -- strike twice?

Nancy Mace's tightrope walk pays off in Trump proxy war

Totally flipped dynamics greeted South Carolina's 1st district, where Trump was wholly unsuccessful in booting a challenger in Rep. Nancy Mace, who carried her primary win by at least 10 points. Mace defeated cybersecurity expert Katie Arrington, who beat Rep. Mark Sanford in his primary in 2018 but ultimately lost the race to Rep. Joe Cunningham, who historically flipped the district to Democratic during the slate of "blue wave races." Arrington bet that voters in the low country would see Mace as something of a flip-flopper, first condemning Trump hard after the Capitol insurrection and eventually softening her attacks. But that bet didn't pay off, partly thanks to a bench of heavy hitter South Carolina endorsements for Mace, including former Gov. Nikki Haley and Trump chief of staff Mick Mulvaney.

Another interesting dynamic in Mace's race is the endorsement cold war of sorts. The proxy battle between potential 2024 candidates -- Haley and Trump -- falls squarely in Haley's camp, the beginning of a nice set up for a highly gossiped about bid for the White House. So far, a good record for Haley, who said in the past she'd bow out if Trump decides to run. But if Haley notches a few other primary wins, who knows? There may be a spot for her against Trump after all.

'Big lie' gets big win in Nevada senate race

Voters in Nevada seem to not be scared of a little election denial. Former Nevada Attorney General Adam Laxalt's open embrace of conspiracy surrounding the 2020 presidential election helped him notch a win in the state's GOP Senate primary. Laxalt, who hails from a state political dynasty, bested political outsider Sam Brown who tried to paint Laxalt as cozy with party insiders.

Still, a roster of Republican stars, nearly all of whom are rumored to join the crowded contest for president in 2024, backed Laxalt's bid, including Florida Gov. Ron DeSantis, Sen. Ted Cruz, Sen. Tom Cotton, and former Secretary of State Mike Pompeo.

He'll see if that flock of support will be enough to kick Democratic Sen. Catherine Cortez Masto out of office. She's sailed to the general election contest with no serious Democratic challengers but now must answer not just to Laxalt but to voters increasingly frustrated with the concurrent fallout of the pandemic, inflation, and other economic woes that have hit the tourist-driven state.
