This took me a hot minute, but here is the White Male Only map (according to CNN's exits):
Electoral Vote:
McCain 408
Obama 109
Tied 21
Popular Vote:
McCain 57%
Obama 41%
Others 2%
Barack would be screwed in the old days.
White Female Only map coming later...
In 2008 in Louisiana, Mississippi, and Alabama, the Democratic Party was effectively the
Black People's party and the Republican Party was effectively the
White People's Party. That itself suggests political pathology because it allows politicians in "safe" districts that vote strictly on ethnic lines that so long as they have the right ethnicity they can preserve corrupt political machines for fun and profit as well as certain re-election. One study showed that Mississippi is the most corrupt State in the Union, and that Louisiana isn't far behind.
Look at the case of William "Cold Cash" Jefferson, D-LA. In a safe district he could get re-elected despite having been caught with the proceeds of bribes in his freezer. It took two tries to remove him from office through the electoral process. But that's the US Congress... just imagine how corrupt a county government or a city council can be when ethnic machines, white or black, can't be dislodged because people within that group (and white people and black people are no less guilty at that) won't vote for someone of the other ethnic group at the least as a temporary protest against incompetence or corruption.
Obama would not have won without lots of white people deciding that his ethnicity mattered little. That did not hold in the South -- except in Virginia, North Carolina, Florida, and to some extent Georgia.
