That was then, not now. He's too old, he has too much baggage, and the obstruction by the opposition will just be worse, so not enough will get done to fix the country and after 4 years of Biden it really will need fixing, IMO.
I'd like to say that not anything Democratic is bad- they did have Kennedy at least, but after 2 years of Democrat control of all 3 elements of government, I can't think of anything good they've done other than would also have been good under the GOP. However, I can think of a lot of bad that they have done.
BTW, I'm really really really happy that she didn't win. He was worth it just for that alone.
