David Axelrod: “I think he needs to debate. This is a close race. Everyone's seen these polls. They have their own polls. He knows that…”

This is another norm that's just going by the wayside in the era of Trump. But, I don't think it has particular meaning.

I think vengeance is very real.

Donald Trump doesn't believe in rules and laws and norms or institutions. He doesn't believe them domestically. He doesn't believe in them internationally and he has defied them to get to this point and back to the presidency.

Everyone who's watching this should strap on their seatbelts because this is what the next four years are going to be like.
