I think we need someone to stop the spending...and pull the wheel of the car to the right or the left.
Is Trump the one? Maybe not. But no mainstream GOP or DNC candidate will turn the wheel away from the cliff, so it seems worth the risk.
Plus, it's not like we haven't seen him in office before. None of the horror stories they tell of Trump happened during the first presidency, so what makes anyone think that crazy things will happen the second go-round?
Biden is a non-issue. He is not in charge. So, criticisms of him are actually irrelevant to the election. I'm not sure who is actually president when he is president. He is a shell, and not actually running the country. I do think his handlers have insane views of the country, and may actually support Iran and Hamas (White House walkouts, calls for restraint that they couldn't justify for the US, etc.). Crazy stuff.
