Coming from Illinois I have first hand experience that the majority of D voters are either stupid and/or corrupt.
As for D politicians, they learned a long time ago that the best defense is a good offense. Look at everything that they have accused Trump of.
Yes, and a lot of them have read Alinsky. “Accuse your opponent of what you are doing”. That makes it harder for them to accuse you. Dem politicians know about the gullibility of Dem voters. Useful idiots are necessary for any socialist or communist revolution.
