Cities vs. rest of county

[SingingAnalyst]

None of the Metro Detroit results should surprise anyone.
Detroit: Total vote 250,219, Biden 93.48%, Trump 5.06%
Rest of Wayne Co: Total vote 623,799, Biden 58.23%, Trump 40.38%
Within Wayne County, Livonia, once a virtually all-white suburb (it voted 67.6% for Bush in 1988), is now quite diverse and voted 50-48 for Biden. Downscale Garden City, once working-class "heaven" (it voted 54.7% for Bush in 1988) was a Trump enclave: it voted 52-46 for Trump while all surrounding communities voted for Biden.

In Oakland County, Lathrup Village, once a GOP enclave surrounded by Southfield, went nearly as strongly for Biden (86.3%) as did Southfield (86.9%). Huntington Woods, a left-leaning, liberal Woodwardside community with only a small minority population, voted 81.8% for Biden, marginally more than neighboring Oak Park, heavily Jewish in the 1950s and now home to many Blacks and Middle Easterners as well as Jews; I suspect the large concentration of Orthodox and Hasidic Jews pulled Biden's vote share down in OP slightly. Funky, gay-friendly Ferndale voted marginally less for Biden than either HW or OP, but still gave him 78.8% against Trump's 19.2%. The formerly GOP enclave of Farmington gave Biden a higher vote share than decidedly downscale Hazel Park, which borders 8 Mile Road and Detroit, as did trendy Royal Oak. Bloomfield Hills went Democratic for the first time since becoming a city in 1932, as did Troy and Rochester Hills. Even Rochester proper, currently an upscale white-flight haven, voted narrowly for Biden. Waterford Township, however, stayed with Trump, as did northern and far-western Oakland County.

In Macomb, which Trump carried 53.3-45.4, Eastpointe, with its large and growing Black population, voted 3-1 for Biden; communities S of M-59 split about evenly, while north of M-59 it was all Trump.

In Washtenaw County (Biden's best county in MI), highly-educated Ann Arbor gave Biden 87.4%, marginally more than neighboring Ypsilanti (86.2%), which is much more downscale and heavily minority. The balance of Washtenaw went 64-34 Biden.
