A lot of normies bitch about our caucus system in Iowa, but you'd be amazed how well it neutralizes outside political operatives, MSM and shill fuckery of all kinds.
When you have to sit down with the other members of your own party and justify your support for a candidate, the glowies start glowing. If you want an example of how well it works, just look at what happened to Lyin' Ted's campaign when he had his precinct captains put the fake word out that Ben Carson was bowing out and his people were breaking Cruz, and then got caught red-handed.
