I tell ya what this inspired me to do.
My manager is a Republican and worked as an election poll worker in his state (won't say where, but we live in different states). I talked to him earlier today and he said he didn't notice anything shady at his polling booth.
That said, the way things have gone today, its kind of inspired me to do my part and become an election poll worker myself for the next election. I live in a true blue state, so I doubt I'll encounter much, but one way I can help prevent shadiness is participating myself because I know I'm not going to do anything against the rules, and I am more than willing to call out when I see it.
