I'm not sure what Obama is up to but he knows how to win
This is a different time with locked in tribes on each side. I think Obama is wrong. You need a really energized base to match the MAGAt fanatics and I don't think a "moderate", "centrist" is going to get people knocking on doors. Everyone knows the democratic party tipped the scales in 2016 and got us trump and they won't tolerate it in 2020. They'll just STAY HOME!
