Yes, very much so, in my opinion. It would just be a turnout game between rural and urban places. You would probably see the GOP campaigning in Laguna Niguel, CA and the Democrats campaigning in New York, New York.
Exactly. Democrats would concentrate on the big inner city areas while republicans would focus on the suburban areas that still vote GOP as well as small towns and cities, which is the real GOP base. So for example in California candidates would obviously visit the LA area as well as the bay area, but also other big centers like San Diego and Sacramento. In addition a republican candidate is likely to swing by a place like Bakersfield or Fresno, while a democrat might go down to the Monterey bay region or out to SLO/SB. But I doubt either candidate would go to a very small place like Redding or Eureka. Also any rural area that does get visited will likely be close to a major city or will be on the path the candidate was already taking in order to transit from one city to another.
