Remember only 66 percent of the voting population voted in 2020. Which means one third of the voting population chose not to vote. Also remember that 60 percent voted in 2016 so there was a six percent increase.
Why the increase? Could it be that we had a very polerizing president? Someone who people ether love or hate the people who hate him would vote for a limp piece of bread if it was running agianst him.
Is Biden popular? No. Did Biden motivate people to vote for him? No. Do I believe that 80 million legal Americans wanted Trump out of office? That they thought Biden was less of a threat to the country? Yes I do.
Biden didn't win because he was popular. He won because he wasn't Trump. And I think that is what really angers them. The loss was all Trump and nothing else.
