We might disagree on rigged, to me "mainstream" Republicans attempting to elect a "mainstream" Republican candidate isn't rigged, just politics as usual. And they lost. Rigged to me is when the dead people in Chicago vote in three different precincts.
I disagree. It’s rigged. When there’s so little connection between who wins and who the delegates are, it’s intentionally open to abuse. “Politics as usual” just doesn’t cut it with US citizens anymore, both political parties.
