Perfect example of "if at first you don't succeed". First time he ran, his wife died and he pulled out of the race, second time he built up the courage almost 20-30 years and had to go up against a Young Barack Obama and Hillary Clinton and lost, third time, they say he's too old and "senile", they say he's terrible and all this hate, so Biden gets his ducks in order and comes out swinging for the fences, and wins.
You couldn't pick a more difficult time to run for president, especially given everything that has happened in the last 4 years. Biden planned carefully, was courting governors and state officials of districts and states just for this moment. I'm happy for Biden.
