The Democrats' Biggest Problem for 2020 - and Beyond

By clustering in cities, even small ones, they have weakened their political impact.

In 2016, Hilary Clinton needed about 5 percent, and that she would get that and become president. She ended up with 2.1 percent, and it wasn’t enough.

Clustering of Democrats has only gotten worse since then, guaranteeing over-sized wins in cities, and overall defeat resulting from losses everywhere else.  Rural bias got Trump elected and could do so again, even if he loses the popular vote again.
