Republicans continue to win big in the South in Presidential elections, but struggle to compete in most of the rest of the nation. In short, the South appears out of touch with the rest of the country. The South exerts a reactionary pull on the Republican Party, leading to it endorsing many issue positions which are losers nationwide. Whether this difference between Southern Republicans and the remainder of the nation is primarily racially-based, or religiously-based is unresolved.
It is clear that Southern whites are decidedly more conservative than the national electorate on a wide range of issues. While Republicans win an overwhelming proportion of the vote among white southerners, the white vote splits much more evenly in other parts of the country.
