Believe it or not, Blacks do not vote for people based on their skin color. Same with Latinos.
Were you in a coma during the 2008 and 2012 elections, or are you just being naive?
Do you seriously think any of the people on bronz4141's list could win the black vote against Hillary Clinton in 2016, just by being black?
Obama won the black vote in 2008 and 2012 because:
1. His background and life story.
2. He was the Democratic nominee.
3. His campaign rhetoric and policies.
4. Who his opponents were.
5. He's black.
He could have won it both times with just the first four of those five, but the fifth is what the sealed the deal.
I am not denying they're other factors involved, but considering enthusiasm and turnout in the black community relative to historical norms (and understandably so) its hard to argue that black voters did not consider skin color as a factor at all.
He certainly got a little higher black turnout than usual because he's black, but the main overarching reason Obama got >95% of the black vote is because he's a Democrat, not because he's black.
If the GOP nominated Condeleeza Rice, it would be interesting. I would not be surprised if black female voters shifted to the GOP in significant numbers if Rice were the nominee.
Rice getting 15% of the black vote is a pipe dream, although I agree she would be the best possible GOP candidate to get a few extra black votes. Of course her strong association with the Bush administration probably makes her unelectable if she somehow ever got the nomination (which is also pretty unlikely).
