Democrats' best path is back to the future

There have been three big elections since 2016. The Democrats have won all of them, but it is the way that they won and the people they won with that give them some reasons for hope.

In purple Virginia, Gov. Ralph Northam’s seven-point win was not unexpected, but it was larger than expected. In Alabama and in Pennsylvania’s 18th Congressional District — a state and a district that Trump had won easily — Sen. Doug Jones, D-Ala., and Rep. Conor Lamb, D-Pa., had to overcome deficits in the 20 point region to win.
