Florida Republican Gov. Ron DeSantis roared to victory in November of 2022, being reelected with nearly 60% of the vote.

Yet DeSantis' presidential campaign has been far less impressive, and some observers are now suggesting that the governor may soon drop out of the race. 

Former White House speechwriter says DeSantis will endorse Trump

Among them is author Douglas MacKinnon, who served as a speech writer under Presidents Ronald Reagan and George H.W. Bush.

In an op-ed piece published by The Hill this past weekend, he claimed to "have heard from two people very familiar with the DeSantis campaign — a major donor and a high-level political operative."

MacKinnon said that his sources told him "that if the Florida governor loses the Iowa caucuses to former President Donald Trump as expected on the night of Jan. 15, he will either drop out of the race that night or make his announcement the next morning. "

What's more, the former White House speech writer wrote that two campaign figures believe  DeSantis will "very begrudgingly" throw his support behind former President Donald Trump.

Sen. Tom Cotton says country has "gone to hell" under Biden

MacKinnon noted how such an endorsement would come on the heels of a slew of other endorsements that have been offered in recent weeks.

That includes one from Arkansas Republican Sen. Tom Cotton, who threw his weight behind Trump last week. Cotton told Fox News that America has "gone to hell" since President Joe Biden took office.

Other major figures to endorse Trump include House Majority Whip Tom Emmer, House Majority Leader Steve Scalise, and House Speaker Mike Johnson.

Although a spokesperson for DeSantis' campaign provided a statement to The Hill that categorically denied that the governor has any intention of dropping out, MacKinnon thinks his departure is only a matter of time.

DeSantis is running at a distant fourth place in New Hampshire

He pointed to the RealClearPolitics national polling average which gives the former president a "jaw-dropping" 62.7% support level.

Meanwhile, former United Nations Ambassador Nikki Haley is second at 11% while DeSantis comes in third place with "an embarrassing" 10.9%.

MacKinnon pointed out how it would not "make sense" for DeSantis to visit New Hampshire where he is currently in fourth place behind Trump, Haley, and former New Jersey Republican Chris Christie.

"After Iowa, more endorsements will flood toward Trump and more donors will run from DeSantis," the author went on to predict.
