Q: Why does it make sense for treasonous, Fascist Progressive corrupticians to habitually pander to invaders IF the invaders aren't voting in our elections?
A: Because the invaders ARE voting in our elections in states like Fascist-controlled Commiefornia.
Q: What keeps Fascist Progressive's beloved invaders from illegally voting in our elections and negating the votes of citizens?
A: Nothing but the lack of a Driver's license or state I.D. that allows them to register to vote.
Q: Why are "Blue States" like Commiefornia so adamant about insuring invaders have driver's licenses?
A: Because no proof of citizenship is required to obtain a license or register to vote. Possessing a driver's license--de facto, faux citizenship--will allow any invader to register to vote and vote in our elections.
