Warning sign for Democrats: While overall turnout was up 12% from the 2014 gubernatorial primary, the increase was concentrated in only 9 counties, with the counties around the D.C. metropolitan area making up almost all of it. 15 counties saw declines in turnout, including every county on the Eastern Shore. It's similar to what we saw in Virginia with Northam's win heavily on the backs of metropolitan areas. The party's infrastructure in non-metropolitan areas continues to atrophy.
Northam won less counties than McAuliffe did but managed to win by a far wider margin and win many more legislative districts as a result. I think any sane person would opt for the Northam coalition every time
Also, like VA and elsewhere, many of these rural counties are losing population and voters
