Has the American education system dumbed down enough generations to allow an extreme left wing power grab via uninformed citizenry?

Yes. Take a look at the responses on this site. Many don't even know why they are voting for pedo Joe other than 'he's not Trump'. That right there is what I call mental retardation. 

Conservatives are the uneducated ones

This is true it needs something done about it 

lol... the first idiot who answered doesn't know English. He posted a question that said "would of", apparently not knowing that it's "would have" --- OR, the contraction: "would've". It is NOT "would of". Yet, here he is, saying something needs to be done.

As for your question: go look up the state educational rankings for the US. 

The American education system has dumbed down enough generations to vote for Trump because they are so brainwashed to be scared of socialism and communism.. even though Biden is almost too moderate for some democrats. Right wing people live in the irrational fear of socialism and communism taking over our country and everyone else is laughing at them for it
