Another detail from that Kos poll on birtherism. It turns out, less than surprisingly, than the cradle of the birther faith is in the South. Just shy of a majority of Southerners — not just Republicans, but everyone — believe Barack Obama was born in the United States. 47% of Southerners say Obama was born in the US; 30% aren’t sure; and 23% say Obama was not born in the USA.
