The problem that conservatives have is thinking that the democratic politicians are stupid. They are not stupid. The people voting for them are stupid.
Think about this, the democrats were smart enough to steal the presidential election and the republicans didn't or couldn't do a darn thing about it. Never underestimate an opponent.
NOTE: I'm not defending the democrats just stating something that is painfully obvious. And it really pains me to have to admit that.
So pardon me while I go slip into something flame-retardant.
I agree, however I do feel it noteworthy that it was years in the making and Republicans constructed large portions of the effort. Without Republicans they wouldn't have been able to pull it off. (Not for lack of intelligence, but lack of resources)
As you said, their voters are ignorant. Willfully so, Republicans are largely the same. It's a sad state of affairs and I don't expect it'll be getting better without some unpleasantries.
