Most people that die are old and white.
Old white people vote Republican in the majority.
Young non-white people vote Dem > 70%.
So the trend is against us, at least to my view.
There are still old White Dems, old black people, old hispanic people, old all other people that die as well.
Young people vote Dem unitl they start working and paying a lot in taxes, then they vote Republican.
Well, a complaint sometimes heard from black politicians is that in the SS system, black men are financing the SS of white women because black men have one of the lower life expectancis and white women the highest.
People of all groups die, and I think whites in general have longer life expectancy than minorities. I don't think your statement means much. Minority voters don't live as long as white voters on average. Actaully, that gives an advantage to white voters as they have longer life expectancy and vote in more election cycles.
And, many liberal young whites become wiser as they age and are conservatives in the 30s or later on.
