Because FOX alone wouldn't have the juice to keep him the spotlight for long in any case. Instead, it was the Jan 6 committee, countless probes by prosecutors who hate the guy, and other Democrats, along with the MSM gushing over every blow Trump was given, that kept him front and center. It was CNN, MSNBC, CBS, ABC, NBC, NPR, and the like along with Democrat politicians that were out to get him that made and kept him a national figure.
Hillary disappeared from the stage after her loss. There's been little media coverage of her. Obama is the same way. If the Democrats and Leftist media had ignored Trump he'd have disappeared too. But they didn't. They couldn't let go, and here we are with the asshole poised to potentially win another election as president.
The choice of Biden was the Democrat's doom. In what should be an easy coast to another term in 2024, they are poised instead to lose the election because they ran a senile retard.
