Voters in half a dozen states went to the polls Tuesday. The results highlight the ongoing conflicts within both parties ahead of the November midterms.

Democratic primaries in Wisconsin, Minnesota and Connecticut signaled what the party's base may want from new leaders: a harder line against President Trump's immigration crackdown and younger, more progressive nominees, as a 14-term congressman was swept aside by a candidate under 50.

On the Republican side, the night tested how far Trump's endorsement still carries, even with his approval at a second-term low, and the answer was mixed. His endorsements won in some states and stumbled in others.

The president sees mixed results as kingmaker

Trump-endorsed candidates in South Carolina's Senate primary and Wisconsin's gubernatorial race performed well Tuesday, highlighting that even amid his lowest approval rating in his second presidency so far, voters still have an ear for him. But Trump's pick for Minnesota's governor struggled Tuesday.

In South Carolina, the Trump-endorsed Sen. Darline Graham advanced to a special Republican primary runoff election for the U.S. Senate despite competing with several GOP heavyweights in a crowded race, according to a race call by The Associated Press.

Graham will now face Rep. Ralph Norman in the Aug. 25 special primary runoff. Norman, who also advanced Tuesday, is a member of the House Freedom Caucus and had endorsements by GOP Sens. Mike Lee of Utah and Rick Scott of Florida.

Soon after she was appointed to the seat in July to complete the term of her late brother, Lindsey Graham, she announced that she was running for the full-term Senate seat on the president's encouragement. Trump held a tele-rally for her this week and said: "[She] will help us achieve our mission to make America great again,"

While no candidate was on track to win the majority needed for the Republican nomination, Graham competed in a crowded field of experienced policymakers and finished first with about a third of the vote. Two thirds of Republicans voted for Norman and Rep. Russell Fry, who were not endorsed by Trump.

In Wisconsin, a swing state, Republican Rep. Tom Tiffany, who voted against certifying the 2020 presidential election results back in January of 2021 and denied the 2020 presidential election, won his party's nomination by a landslide, in a race called by the AP Tuesday night.

Tiffany had Trump's endorsement and a united Republican backing.

Rhett Marques, an Alabama state representative endorsed by Trump, also clinched the Republican nomination for the congressional district that runs from Mobile County through the southern Black Belt to the Georgia border.

However, in Minnesota, Trump had endorsed Mike Lindell, a staunch Trump ally and the founder of MyPillow, a pillows and bedding accessories company, for the GOP gubernatorial primary, and he lost his primary to Lisa Demuth, the speaker of the Minnesota House.

Lindell had faced questions about residency requirements from the Republican Party of Minnesota and allegations that he physically abused a former girlfriend. He has denied both claims.

Demuth, 59, has presided over a state house that was almost evenly divided between Republicans and Democrats and has billed herself as the Republican with the best chance of winning in the fall.

She will face four-time Sen. Amy Klobuchar, who won the Democratic gubernatorial race Tuesday night. Klobuchar announced her decision to run for governor after Gov. Tim Walz abandoned his bid for a third term in January.

Minnesota's Republican Party has not won a governor's race in two decades.
