true - I was just going back to '18 to get a number on a non-presidential year Senate race/turnout.
But not all of surburbia is necessarily favorable ground for Dems either. Depends on where people came from to get there. We've got Macomb county which is suburbia, as is the area in MN that elected Michele Bachman just as another example I remember when I lived there.
The racial makeup similarity is interesting. Still a lot of cultural differences remain, with the Texas heritage being ranching and even more so the oil field, vs the California heritage being agriculture, entertainment and now tech. This produces a lot of difference in the world view of the professional classes in the two places. Also with CA being renowned for its educational institutions, Tx not so much.
