Hamilton trended heavily D between 2012 and 2016 (15 points to the left) but it’s pretty unlikely that it will trend 15 points D again in 2020 simply because it’s uncommon for an area to trend heavily toward the same party two elections in a row.
Lmao Hamilton literally did just that in 2016 and 2018.
Since you are so certain about the political future of suburbs, how do you explain Williamson County, TN trending Republican from 2016 PRES to 2018-GOV and 2018-HOUSE, relative to both the nation and the state as a whole? Williamson, TN is probably the archetype of a red-state, deeply conservative, well-off, suburban county.
