I guess you could say most of the state has gone nutty since I lived there in the 60’s.
There’s still some sane parts. The Plains counties, for example. Some went over 80% for Trump (Baca, Cheyenne, Kiowa, Kit Carson, Washington & Yuma). Even Moffat & Rio Blanco in the NW corner of the state also went over 80%. All of these were record-breaking highs for a GOP Presidential candidate. Not even Nixon in ‘72 or Reagan in ‘84 got those kinds of percentages.
Some Hispanic (plurality or majority) areas also went for or were trending to Trump. He carried Trinidad’s Las Animas County with 55%, which last went GOP in 1972 (that appeared to be the highest % for a Republican in over a century). Same with Pueblo, also the first since 1972. All evidence of working-class appeal, Reagan and the Bushes couldn’t get these counties.
The downside is they’re offset by the Democrat areas of Denver and the resort areas. Still, if Trump holds his appeal in those areas and peels off some suburban Denver counties and keeps the Dem margins down elsewhere, he could win the state in 2020. As it was, Hillary got just 48.2%, down from a high for Zero in 2008 of 54%.
