Uh oh. Kathleen Parker is rattling cages again: Sen. George Voinovich and the GOP as a Party of the South.

Not all Southern Republicans are wing nuts. Nor does the GOP have a monopoly on ignorance or racism. And, the South, for all its sins, is also lush with beauty, grace and mystery. Nevertheless, it is true that the GOP is fast becoming regionalized below the Mason-Dixon line and increasingly associated with some of the South’s worst ideas.

It is not helpful (or surprising) that “birthers” — conspiracy theorists who have convinced themselves that Barack Obama is not a native son — have assumed kudzu qualities among Republicans in the South. In a poll commissioned by the liberal blog Daily Kos, participants were asked: “Do you believe that Barack Obama was born in the United States of America or not?”

Hefty majorities in the Northeast, the Midwest and the West believe Obama was born in the United States. But in the land of cotton, where old times are not by God forgotten, only 47 percent believe Obama was born in America and 30 percent aren’t sure.

Southern Republicans, it seems, have seceded from sanity.
