Odds are really good he’ll die of a heart attack while in office, but unfortunately that means Vance becomes President and that’s honestly even scarier than Trump. Vance couldn’t have won by himself, but the amount of damage he could do when handed the presidency is staggering.

What resistance they provide is mostly performative, as their real priorities are dictated by what the large corporate donors are paying for.
