republican party realignment

The Republican base, the true "red America" is now mostly limited to the deep South, which is made up of and controlled mostly by racists that have converted to the Republicans. The libertarian West is wary of Republicans in bed with the Southern Evangelicals. More states are now more blue than red. So is the populist MidWest, which distrusts the GOP alliance with big business and multinational corporations.
The bottom line is that the Republican Party has become the party of Rove and Bush, who appeal mostly to the Southern Bible Belt.
