Former President Donald Trump has not yet announced another White House run, but more and more signs suggest he’s testing the waters ahead of a 2024 campaign announcement.

Trump’s post-White House super PAC, Make America Great Again, Again, recently commissioned a head-to-head poll pitting the 45th president against his successor, President Joe Biden. The poll, conducted between Nov. 11-16, showed Trump besting Biden in Arizona, Georgia, Michigan, Pennsylvania, and Wisconsin, all states that were critical to Biden’s 2020 victory.

“Poll after poll clearly demonstrates that former President Donald Trump is still the 800-pound gorilla in the GOP and would be its 2024 nominee should he run,” Tony Fabrizio, who conducted the poll on behalf of MAGAA, told Politico of the results. “This new data clearly shows that today the voters in these five key states would be happy to return Trump to the White House and send Biden packing.”
