They dont care.
Not too long ago I was arguing with a liberal about the stolen election. He said to me that while he doesnt believe that Biden won thanks to cheating (I didnt believe him that he believed that), if Biden did indeed win due to voter fraud, he’s ok with it “as long as it got trump out of the white house.”
True. The ONLY “morally right thing to do” was to get Trump out of the White House.
NOTHING else mattered. NOTHING else was acceptable.
So in short, they don’t believe in elections, or representative democracy as a way of resolving differences.
