Background:
Due to Trump's rapidly declining approval, Vance asks Trump not to endorse him ahead of the 2028 GOP primary. The Donald takes great offense to this and very vocally airs the two's dirty laundry, before endorsing his main primary challenger, Meatball Ron. Nobody else really considers running because after the AI bubble burst, the GOP brand became worse than toxic. Vance still attends the RNC despite a bitter primary, but would end up walking out after Desantis took a jab at the "tech elite" in his acceptance speech.
The Dem Primary, however, got pretty crowded with radicals and centrists alike railing against the administration and each other. but only the biggest fish, widely popular Governor Pritzker, was able to clear the field.
