Donald Trump told conservatives Sunday he was considering running for president again in 2024, as he reasserted dominance over the Republican Party and warned of a "struggle" for America's very survival.

Echoing the grievance politics of his 2016 campaign and the harsh rhetoric of his one-term presidency, the 74-year-old fired up an enthusiastic crowd at the Conservative Political Action Conference in Orlando.

In a keynote speech - his first since leaving the White House on January 20 - he repeated his false claims that he won the election instead of President Joe Biden, and hammered establishment Republicans who voted against him in the latest impeachment drama.

But while he teased his future plans, he left the crowd guessing about whether he will challenge Biden in a rematch.

"With your help we will take back the House, we will win the Senate, and then a Republican president will make a triumphant return to the White House - and I wonder who that will be?" the former president said to a raucous cheer.

"Who knows?" he boomed about his potential plans. "I may even decide to beat them for a third time, OK?"

Banned from Twitter and other social media, Trump has maintained a low post-presidential profile at his Mar-a-Lago resort.

At CPAC, he walked on stage to revel in a lengthy standing ovation by cheering loyalists, the vast majority maskless despite the COVID-19 pandemic.

Like he did so often during his two campaigns, he painted a pitched battle against the Democrats' "socialist" agenda to remake the nation.

"We're in a struggle for the survival of America as we know it," Trump said. 

But he said the "incredible" populist movement that propelled him to victory four plus years ago is just beginning, "and in the end, we will win."

Trump also put to rest the rumors that he might take his base of support to create a new political party.
