First off, I said "[t]wo separate factors could give Bush a landslide victory." Meaning the Christian vote and the black vote. In addition, the get out the vote efforts by both the Dems and the GOP have been quite significant this time around. So there will be more Americans voting overall and therefore, more black Amewricans voting too.
>>>> ... but since most of the black vote is located in the south, states that Bush will probably sweep anyway, its effect is even further diminished.
According to 2003 data from the Census Bureau, southern states contain about half of the entire US black population. So everything considered, I believe if Bush doubles the amount of total votes he garners with black America, that will be a big plus in his overall election victory.
More than half of the Gore voters in Alabama, Georgia, and Louisiana were blacks, states which he lost quite handily.
I'm not meaning to diss your post. More than doubling black support for Bush in this election could signal an end to plantation politics in this country.
But I can't find a single state where it would make a difference in the electoral outcome.
