President Donald Trump got his mojo back with Republican primary voters Tuesday following a setback in Iowa last week when his preferred candidate lost the GOP contest for governor.

Trump-backed House candidates notched wins in South Carolina and Nevada. South Carolina Sen. Lindsey Graham overcame a primary challenge from a conservative insurgent.

And South Carolina Lt. Gov. Pamela Evette, Trump’s pick for governor of the Palmetto State, came in first in the gubernatorial primary. She, however, did not secure the majority needed to avoid a June 23 runoff, when she’ll take on state Attorney General Alan Wilson.

“President Trump’s endorsement remains the most powerful force in Republican politics because voters trust his leadership and support candidates who champion the America First agenda,” Kiersten Pels, the national press secretary at the Republican National Committee, said in an email. “His endorsement has repeatedly driven turnout, energized low- and mid-propensity voters, and unified Republicans behind winning candidates.”

While the president has been dogged by flagging poll numbers and asserted recently that he doesn’t care about the midterms, Pels said Trump and members of his administration “will continue working to deliver victories up and down the ballot.”
