Why on earth do you apparently think Biden is some kind of crazy leftist? He's about as centrist as they come.
I fail to understand why anyone's concerned about Biden's age, but not Trump's. Trumpty's three years younger, which is insignificant. He also rambles senselessly at his rallies. Is no one concerned about his mental health? Aren't there enough people who won't vote for Trump in ANY conceivable circumstances?
Alaric, the original barbarian who sacked Rome, was far more civilized than Trump and his crazed followers.
