Trump airs grievances,teases 2024 run in post-presidential speech

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.

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 coronavirus pandemic.

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

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.

But he also took aim at Republicans he feels betrayed him -- a strong signal that he will seek to help oust them in upcoming elections.

Trump remains the most potent force in the Republican Party, something he made clear he was acutely aware of Sunday when he described his own endorsement as "the most powerful asset in politics."
