Party leaders don't expect any last-minute efforts to deprive Donald Trump of the nomination at the Republican National Convention, even in the event of "some crazy hypothetical."

A group of delegates attempted to keep him from securing the nomination at the 2016 convention, but party leaders say there's little opposition to the former president this time after he rolled to easy primary wins in Iowa and New Hampshire, reported NBC News.

“It didn’t happen then, and it’s not going to happen now,” said David Bossie, a Republican National Committee member and longtime Trump ally. “There is no one who is going to attempt to do that. ... There’s none of that conversation that has happened in here. Not one iota of it.”

Trump's opponents tried eight years ago to allow delegates to be released from their obligation to the former reality TV star in an effort to make Sen. Ted Cruz (R-TX) the nominee, but the leader of that effort – Kendal Unruh of Colorado – has since left the Republican Party.

“The people who I was fighting alongside with in 2016 — those people are now fully onboard with Trump,” Unruh said. “He has a lock on [the nomination].”

Nikki Haley remains in the Republican primary, but one RNC member said there's no chance that she could assemble enough delegates at the convention to keep Trump from getting the nomination.

“Just ’cause she stays in does not automatically make it hers,” the RNC member said, adding that he could see another failed GOP candidate getting the nod in the event of “some crazy hypothetical."

“Ron DeSantis, who is a successful governor and, you know, came in second in Iowa and then had the class to get out, is someone who people would turn to immediately,” the RNC member added. “That’s never going to happen — that is not a scenario.”
