African-American and Hispanic voters are catching on that the Rats have been using them, but not representing their economic interests. Many get it, and are joining MAGA.
I think the influx of illegals is part of it......many are catching on that they too are being replaced. I think the obviously corrupt lawfare is part of it. They can identify with Trump more after seeing him be clearly screwed over by corrupt prosecutors and feds. Part of it is just comparing the record. Under Trump we had peace abroad and prosperity at home. Under Biden we have war abroad and a crap economy at home.
