OnPolitics: Trump won the South Carolina primary, tightening his grip on the GOP nomination

Hey OnPolitics readers! Former President Donald Trump's winning streak continued Saturday after he easily defeated former South Carolina Gov. Nikki Haley in her home state's primary.

By handily winning the Palmetto State − where voters twice elected Haley as their chief executive − Trump may have sent a final, decisive message that he remains the GOP's top dog, USA TODAY’s Phillip Bailey reported.

Here's what you need to know about the pivotal primary and Republican reactions:

❓Is Haley staying in the race? Haley repeated her promise to stay in the race on Saturday, reiterating that she doesn't believe Trump can defeat President Joe Biden in the fall and that the roughly 40% margin of the vote she held is significant.

🔴RNC member standing up to Trump: One shot in the arm for Haley’s long-shot bid could be a move by a Republican National Committee member who wants to stall Trump’s takeover. Henry Barbour, a national committeeman from Mississippi, submitted two draft resolutions: One that says the RNC must remain neutral for the remainder of the primary and another that the RNC will not pay the legal bills of any candidate.

🔜The Michigan primary is up next: The 2024 presidential election now turns to Michigan, where both parties will hold their primaries Tuesday. That gives Haley another bite at the apple, but just as intriguing will be a fight on the Democratic side. Democratic Rep. Rashida Tlaib, has been rallying urging progressive voters to pick "uncommitted" over President Joe Biden due to his support for Israel in its war with Hamas in the Gaza Strip.
