Who would theoretically vote for the Republican Party from Fremont through Trump

[🐒Gods of Prosperity🔱🐲💸]

A few small regions that have been pretty consistently good for Republicans since 1856:

- northern Illinois, around Rockford to the south and east, and then on up north across the border to Walworth Co, WI.

- the area north and west of Columbus: the northeast Miami Valley + Delaware County.

- parts of southeast OH along the Ohio River (ex. Meigs Co.)

Dutch in Michigan have always been fairly strongly Republican going back to the beginning, though for whatever reason McClellan won Ottowa County in 1864, and in 1912 West Michigan preferred TR (himself a follower of the Dutch Reformed tradition).

Weren't several counties in eastern Tennessee/southern Kentucky consistently Republican from 1856/60 to 1960?

From 1864-present, but Fillmore in '56 and Bell in '60.
