The general reaction to the Democratic debates is "meh".
Lesser losers: Democrats who are not nominated.
Big loser: The Democrat who gets nominated.
Winner: Trump.

Anyone who goes up against Trump, and loses spectacularly, is finished in national politics. Currently, Trump is very likely to win against any of the nominees. It would make sense for the Dems to nominate somebody who is old and ready to retire anyway.
