Create fictional cities and guess how they vote

[Meatball Ron]

Given above average educational attainment, population density, and lack of religiosity, I am going to say Biden +10-15; the lack of racial diversity and presence of the logging industry suggests a healthy Republican base which is why I wouldn't expect a larger margin. This city has trended D / is continuing to do so, and probably went for Romney in 2012, or Obama by a narrower margin.

Thanks. Please feel free to create a fictional city of your own.

Ah, sorry!

Median Income: $65,200
Density: Urban-suburban

College graduation rate: High

Same as Scott - this is a real city. Take a flier.

Quite Democratic, and trended much more to the left in the age of Trump. Probably gave Obama less than 60% in 2012 but Biden in 2020 a lot more than 60%. (Also, what city is this?)

How about this one?
POPULATION: 59100 (2019 estimate); 58300 (2010 census)
DEMOGRAPHICS (racial): 50% white; 26% African-American; 16% Hispanic; 5% Asian; 1% Native American; 2% other/multiple
DEMOGRAPHICS (gender): 52.7% female; 46.0% male; 1.3% transgender
DEMOGRAPHICS (religious): 27% Protestant; 20% Catholic; 13% Jewish; 7% Mormon; 6% Muslim; 14% some other religion; 13% nonreligious
DEMOGRAPHICS (LGBTA+): 15.3% LGBTA+; 1.3% transgender; 9.5% homosexual (5.5% lesbian; 4.0% gay); 3.5% bisexual; 0.9% asexual; 0.1% other LGBTA+
MEDIAN HOUSEHOLD INCOME: $49,000
MAJOR INDUSTRIES: Biotech; Manufacturing; Government; Tourism; Sales
EDUCATIONAL ATTAINMENT: Postgraduate degree, 25%; Bachelor's degree, 24%; High school, 28%; Less than High school, 21%
REGION: Midwest (not to be confused with the Great Plains)

This town seems incredibly Democratic given racial diversity, high LGBT population, high educational attainment, and biotech presence. I am inclined to think a place like this only exists in the NYC / Boston / SF / LA metros, but you said Midwest, so I'm guessing it's near Chicago, or otherwise some sort of liberal college town (but then education would be a major industry)?

I am going to skip adding a new one because there are a few that nobody has done either of these  yet:
