Predict when the Twin Cities suburbs go 60% DFL and Greater MN goes 60% GOP

[LiberalDem19]

2018 Walz vs. Johnson:

Suburbs: Walz 54-42
Greater MN: Johnson 52-45


I'm thinking the DFL hits 60% in 2028 in the suburbs with growth and increased diversity, although if the GOP moderates post-2020 election, that could change.
I'm not sure about the GOP in Greater MN because of Rochester/Mankato growth. Duluth proper used to be losing population seems to have stopped the bleeding. DFLers seem to be leaving the Iron Range in droves. Gonna say 2030

It won't get that polarized. Eventually the republicans are going to moderate, or the democrats are going to either get AOC-ized or become more populistic.

Taking just two party vote share, and defining 'Metro' as Hennepin, Ramsey, Dakota, Washington, Anoka, Carver, and Scott counties.

Metro

Clinton: 910,214 (60.7%)
Trump: 589,299 (39.3%)

Total: 1,499,513

Outstate

Trump: 733,933 (61.6%)
Clinton: 457,611 (38.4%)

Total: 1,191,544

Greater Minnesota already is going about 60% Republican on average. Whether the suburbs go 60% Dem? doubtful, even though the urban and suburban area combined is already at 60%.

It already sort of is, but I expect a large growth for the GOP in Greater MN cancelling out the effect the more Democratic metro areas.
