They can't pull that trick in every single election. The Roy Moore thing was suspicious as hell and I still believe there was unironic voter suppression, but you have to remember that both the establishment Republicans and all Democrats badly wanted him not to win. On the Republican side part of the rationale was that he would create problems for them in the midterms. My guess is they probably called some kind of temporary ceasefire to fix the special election for Jones. It's one thing to do that in a single special election where a highly controversial candidate is running, it's another thing to try it in every single Senate race in the country and not expect people to figure out what's happening. Even the Democratic party can't believe that Americans are literally that dumb.
Bottom line is if you live anywhere in the US and you have a Senator/Representative/Governor whatever up for election, fucking vote. I don't care how blackpilled you are about the future of civilization or how big a cuck the Republican candidate in your area is or whether or not you think democracy is a bad idea, fucking vote. Every war is won by gaining ground slowly and steadily in a series of small battles, and right now our side is gaining ground. Let's not fuck it up.
