Trying to figure out the 1968 R counties, many of which are pretty liberal. Perhaps they got more Democratic after 18-20 year-olds got the right to vote?
Humphrey was HATED by certain elements of the left.
Which elements? I know anti-war was part of it. Did those people not vote or vote for Nixon? Makes sense that 15/21 of the 1968 R counties voted for Obama in 2012 and included universities as: UC-Santa Cruz, U. of Colo., U. Of Iowa, U. of Oregon, Oregon St., as well as Native Am. Shannon, SD and several Hispanic counties in NM.
