Most:North Jersey, Long Island, Philly, Orange County (CA), Houston, Dallas, Chicago, Milwaukee, Indy, Columbus, Detroit, Grand Rapids, Pittsburgh, Kansas City. Perhaps also the Bay Area and Boston, since those metro areas are so blue that there may be nowhere to go but up.
Least: Atlanta, NoVA, Twin Cities, Austin, Denver, maybe Phoenix
No, a lot of these places, especially North Jersey and OC were only Republican since they promised low taxes, and now they can't even do that anymore, and Dallas is becoming a disaster for the Republicans, despite a relatively abysmal Texas performance, Joe Biden improved on O'Rourke in much of the DFW metro. I do not see a bright road ahead for Republicans in any of these three places.
