southern Republicans

If today's Republican Party can be said to have a center of gravity, it's in the South.

The states that made up the Confederacy account for less than a third of the country's total population, yet in the 2012 election they gave Republicans close to half of their membership in the House and accounted for nearly 60 percent of Mitt Romney's electoral votes.

But in House leadership? There, the South has been underrepresented.
