Describe the demorgaphics of this hypothetical county by voting history

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Seems Midwestern, lower-middle class, average religiosity. Might go further back in time in another one, but for now I'll do another 1912-present.

Historically mining county in Southern Missouri that was pro-confederate during the Civil War. FDR's narrow victory in 1932 is explained by a brief upsurge in Republican support following Hoover's victory in 28.

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Southwestern Idaho?

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

[Make America Grumpy Again]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Probably somewhere in the rural Interior West that is overwhelmingly white and blue-collar, though not particularly religious

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

[Make America Grumpy Again]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Historically mining county in Southern Missouri that was pro-confederate during the Civil War. FDR's narrow victory in 1932 is explained by a brief upsurge in Republican support following Hoover's victory in 28.

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

[Make America Grumpy Again]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Seems Midwestern, lower-middle class, average religiosity. Might go further back in time in another one, but for now I'll do another 1912-present.

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

[Make America Grumpy Again]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Dixiecratic county that increased in population over time. It seems like Mississippi would be the most likely place. More Christian than average and slightly wealthier.

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.

Seems Midwestern, lower-middle class, average religiosity. Might go further back in time in another one, but for now I'll do another 1912-present.

[GregTheGreat657]

A midwestern county that was at one point very rural (see populist vote) but has morphed into the suburbs of a major city and has therefore drifted D.

Like with Christian Man, this county is different from my previous three which were all in NY State (with the first and third being Upstate Rust Belt counties, and the second being a suburban Long Island county)

Getting some Upper South vibes with this answer with Maryland being the most likely state. Average religiosity and above-average but not wealthy when it comes to the average GDP. This one's starting a few decades later.
