Well, he didn't have to wait long... Challenge accepted!

I'll give you my thoughts, in no particular order.

1. If this were anyone else, the election would be over. But keep in mind that Trump doesn't need to outrun the bear. He only needs to outrun his camping buddy. There is still plenty of time for him to dismantle Clinton. If you think things are interesting now, just wait. There is lots more entertainment coming.

 2. This was not a Trump leak. No one would invite this sort of problem into a marriage.

 3. I assume that publication of this recording was okayed by the Clinton campaign. And if not, the public will assume so anyway. That opens the door for Trump to attack in a proportionate way. No more mister-nice-guy. Gloves are off. Nothing is out of bounds. It is fair to assume that Bill and Hillary are about to experience the worst weeks of their lives.

 4. If nothing new happens between now and election day, Clinton wins. The odds of nothing new happening in that timeframe is exactly zero.
