I think the majority of Kamala's voters will come from the abortion side of the ballot. Then you have SS so there is part of, if not an overwhelming majority of the elderly/disabled voters. If Kamala can get a heavy chunk of young voters and possibly some voters from the LBGTQ side, Trump/Vance might end up looking crazy af on election night...
I'm from MI, any time there is a heavy Democratic voter turnout in Wayne CountyDetroit the state usually trends blue regardless of the other counties in the state.
