The probes, which are unfolding in multiple jurisdictions and consider everything from potential fraud and election interference to the role he played in the Jan. 6 insurrection, represent the most serious legal threat Trump has faced in decades of an often litigious public life. They’re intensifying as a new poll from The Associated Press-NORC Center for Public Affairs Research found Trump’s iron grip on the GOP may be starting to loosen.

His popularity among Republicans is declining somewhat, with 71% saying they have a favorable opinion of Trump compared with 78% in a September 2020 AP-NORC/USAFacts poll. But the new poll shows only a narrow majority of Republicans — 56% — want him to run for president in 2024. The poll found that 44% of Republicans do not want Trump to run.

Despite the legal and political headwinds, those around Trump describe him as looking to the future and emboldened by a sense of invincibility that has allowed him to recover from devastating turns, including two impeachments, that would have ended the careers of other politicians. Instead of receding from the spotlight, he’s teasing a comeback run for president as he escalates his attacks against those investigating him and his company.
