This is an excerpt from the same article, and pertains to more than just one voter:
"Louisiana provides a good example. In the 2008 presidential election, 84 percent of whites voted for John McCain. Likewise, in the 2010 Senate election, 72 percent of whites voted for David Vitter. There were no exit polls for the 2012 race, but given the extent to which Romney matched McCainÂ’s performance, you can assume a similar level of a racial polarization.
This story is also true for Louisiana’s neighbor, Mississippi—which saw 88 percent white support for McCain, and 89 percent white support for Romney—as well as Alabama, which had similar totals. And of course, in each of these states, African Americans voted for Democrats in similar or larger numbers".
Even if the black vote had been equally divided between Obama and his opponents in both elections, it did not represent a substantial enough percentage of the electorate to have made a difference in the elections outcome.
In the last election he captured more of the female vote, Hispanic vote, Asian vote, and also votes of first time young voters.
Those votes combined is what made the difference, so I am puzzled as to why a segment of the population that has such disdain for blacks in general cares one way or another what their choices are at the polls.
You're assuming whites voted for McCain because he was white. Yet you have no real evidence of it. Blacks did vote for Obama because of his skin color and many have went on record as said as much.
No, I'm not "assuming" anything, nor do I personally care how they vote. I was just presenting another possibility and something to think about.
There are of course some blacks who voted for Obama based on race, considering that historically, black citizens were denied the right to vote just a little more than 50 years ago, what would any rationale person expect? To people who were living then, (myself included) it was unthinkable that a black candidate could win, let alone run for office.
There are also black citizens who voted based on self interest and not race.
I think it is a stretch for you to insist that the majority of black voters who voted for Obama, did so due to him being black.
If that is the case, they could have just as easily supported Herman Cain.
Anyway, this is all just speculation, because the outcome has already happened.
