Can you describe a hypothetical county....

[It’s so Joever]

With these presidential results since 1980?
         Dem: Rep: Other:
1980: 54.3%-40.2%-5.5%
1984: 52.7%-44.9%-2.4%
1988: 51.9%-47.4%-0.7%
1992: 42.3%-45.8%-11.9%
1996: 53.7%-40.2%-6.1%
2000: 50.2%-47.5%-2.3%
2004: 50.1%-49.7%-1.2%
2008: 54.9%-44.1%-1.0%
2012: 53.3%-45.3%-1.4%
2016: 55.1%-40.7%-4.2%

Obviously these results are unrealistic and such a county doesn’t exist, but try your best.

Polarized county, probably lots of southern whites and blacks. Normally votes D, but Perot managed to flip enough southern white Ds in 1992 for Bush to get a plurality (also because lower black turnout then today).

Not perfect, but as close as I can get.
