Florida Governor Ron DeSantis announced Sunday his decision to withdraw from the 2024 US presidential campaign and support Republican frontrunner Donald Trump in his reelection effort.

Vivek Ramaswamy announced a similar suspension and declared support for Donald Trump following Trump's win in the Iowa caucuses.

In a social media post, DeSantis expressed that due to not having a "clear path to victory" he could not ask his supporters for more time and donations. "Nobody worked harder and we left it all on the field... If there was anything I could do to produce a favorable outcome – more campaign stops, more interviews – I would do it."

DeSantis went on to say that it was evident to him that the majority of Republican primary voters wanted to give Trump another shot, and that, while he had previously disagreed with the former president, he preferred him over Joe Biden.

He explained that he would honor his pledge of endorsing the Republican nominee. "He has my endorsement because we can’t go back to the old Republican Guard of yesteryear or repackage formed have warmed over corporatism that Nikki Haley represents."

Donald Trump is anticipated to secure victory in the initial ballot of the 2024. He maintains a substantial lead in a diminishing field of Republicans competing for the party's presidential nomination, as indicated by the polls. However, the former president faces the challenges of managing elevated expectations and adverse winter weather conditions that may impede voter turnout.

Trump holds the backing of over half of Iowa's probable Republican caucus attendees, as reported by the most recent FiveThirtyEight average of state polls. This lead is anticipated to be formidable, even in a state known for producing surprising outcomes in past caucuses.

US VP Kamala Harris says she is 'scared as heck' of Trump's return

US Vice President Kamala Harris said Wednesday she was "scared as heck" that Donald Trump would return to the White House in the November election and urged Democrats to "fight back."

Her comments came after Trump won on Monday in the Iowa caucuses, the first step in the Republican nomination race to challenge President Joe Biden later this year.

"I am scared as heck, which is why I'm traveling our country... we should all be scared," she told The View show on the ABC network.

But the 59-year-old Harris added, "We don't run away from something when we're scared, we fight back against it."

Harris was responding to a question about reports former president Barack Obama was concerned with the Biden campaign, and to comments by ex-first lady Michelle Obama saying she was "terrified" of a second Trump term.

According to a recent ABC News/Ipsos survey, Trump leads his Republican opponents in key popularity indicators as the 2024 primary season begins, while Biden's job approval rating has dipped to the lowest rating for any president in the last 15 years.

A DailyMail/J.L Partners poll also revealed that six in ten people, including almost one-third of Democrats, believe Biden should not run for president in 2024.
