I'm not sure he's getting more popular as much as his hardcore followers are getting more vocal in their efforts to deny reality.
The numbers of Republican voters who dislike/hate Trump seem to be (slowly) growing, and independent voters are inclining further from him much quicker, His followers may be able to help him and his lackeys win the GOP primaries, but in terms of a general election, Trump's got even less support than in 2020. Anti-Trump Republican voters, may not go so far as to vote Democrat, but them staying home and not voting would still doom Trump's hopes of a return to the White House.
