About half voted for Hillary.
This Obama thing is ripping the Democratic party wide open. 4 out of 5 blacks in SC voted for Obama and they are 50% of the electorate there; if that ratio was 3 out of 5 instead of 4 out of 5 hillary would tie obama in SC.
On top of this, we had the Congressional Black Caucus sponsored debate last Monday where Obama was cheered whenever he answered a question and Hillary was booed. Unbelievable
You see, the problem with Republicans is that they are so divisive, while the Democrats are harmonious.
This explains why the RATS go so far to paint Republicans as racists, anti-black, etc.
The RATS know that if the black vote dropped to even 85%, they would never win another national election. And they would lose a ton of state and local elections as well.
