The Average since 1964 (When Lyndon Johnson cleverly flipped most newly registered black voters to Democrat) is 10%.
Top is 15, bottom is 4. A variation of +/- 5 or 6.
Barack Obama spiked the average down. (because "YAY! MY TEAM!") but when he's gone it will go back closer to 10%.
You take out that first year under Johnson and those last two numbers (Barack) and the average becomes 11.7 with a variation of +/- 3.5 which is D@mn close to my statement of a "few points."
So what's the point? If you are arguing we need to make inroads into the Black community, I agree. I've been arguing since 1994 that we should have picked a black candidate to run against Clinton and so on.
I *KNEW* he would get a massive increase from black voters, (and racist white voters who want to feel good about themselves for voting for someone because of the color of their skin) and I also knew the media would be afraid to hammer him the way they would a white candidate.
It was a guaranteed slam dunk win for conservatism. We could have a historic first, as well as a man who could enact a conservative agenda and we would have ended up routing Liberalism for decades.
All we had to do was run a black candidate and we would have garnered all that support and idolization that the Democrats grabbed by making that choice.
Sure, it's against our principles to judge people by the color of their skin, but in this case it would have served a higher purpose. It would have resulted in a greater good.
Above all else, it would have been a pragmatic solution which would have eventually yielded a principled one.
Sometimes the right man for the Job is one who has the ability to Unify. If skin color is the characteristic that would have rallied the people, we should have recognized this and used it.
But we are the STUPID party.
Al Gore got 90% of the black vote in 2000. Barack Obama got 93% in 2012.
