Former U.S. President Donald Trump's indictment on Tuesday for his alleged role in efforts to overturn his 2020 election defeat will likely fuel his march toward the Republican Party's 2024 presidential nomination, analysts and party strategists say.

"This will rally his supporters to his talking points — about how the establishment and the 'deep state' are against him and against them," Stu Rothenberg, a nonpartisan political analyst, said before the indictment was handed down.

Opinion polls show Republican support for Trump surging since the first of three indictments was issued in March. He is far and away the front-runner, leading second-place Ron DeSantis, Florida's governor, by close to 30 percentage points.
