Who should Democrats nominate under these two scenarios?

[pbrower2a]

Scenario #1: Just about any Democrat will win. That the 2018 election has been a disaster fro Republicans demonstrates that the fears of many Americans that Donald Trump would dismantle democracy have not come to pass. He has provoked mass discontent that has so rent America that even in deep-red areas a populist resurgence has caused people to turn against the Great Poseur.

Scenario #2: If it is Morning in America it is a morning in which the 12-hour workday is the norm. Any Democrat is likely to be the New Walter Mondale in the popular votes, but manages to win just over 100 electoral votes because of California, New York, Illinois, Washington, Massachusetts, Maryland, Minnesota, and several other states with fewer than ten electoral votes. The  American political system might not be democratic, but it needs a show of contention. But the Democrats have never been free to organize, so they have about as much chance as the minor parties in the old DDR or the minor parties in the PRC today.
