WaPo reports: Davis has become a critic of his own party and broken with Democrats on a number of high-profile issues, including voter ID laws. The Republican Party, Davis said in his statement, “is fighting the drift in this country in a way that comes closest to my way of thinking: wearing a Democratic label no longer matches what I know about my country and its possibilities.” The Alabama Democratic Party in particular, he says, “has weakened and lost faith with more and more Alabamians every year.”
