There are all kinda ways to present data, but I thought the following breakdown was interesting.
Voter registration in California among BLACK voters is 83% Democrat.
Voter registration in California among LATINO voters is 57% Democratic.
Voter registration in California among WHITE voters is 40% Democrat.
Voter registration in California among ASIAN voters is 30% Democrat.
That actually is an interesting way of looking at it. I just took the numbers for the Americans from Asia contingent as ~50-50 Republican/Democrat -- but you're right, the Asian contingent has a fairly large number of 'independents' (a.k.a., 'don't ask don't tell')...
I have no idea what is going to get the Americans with black skin, off of the Democrat plantation. Most of the Democrat social policies (Abortion on demand; homosexual 'marriages'; no school choice; general defaming of God) should be anathema to this segment of America -- but they still keep coming back to the same poisoned well during every election...
