Chris Douglas at First Republicans Forum has a good post on what I view as the devolution of the Republican Party. Over the past few decades, the GOP has lost many of its Yankee Republicans as it has become the party of the Southern Conservative.
What was the Yankee Republican? Pro-business, pro-personal responsibility, pro-tolerance, and pro-progress.
. . .
As the Republican Party has moved nationally from Northern Yankee to Southern Conservative in character, it has begun to repel forward-looking people. As the Party slides to the South, perhaps it is we who should be standing athwart it saying “stop” and instead begin directing it back to the Northern roots from which its success in Indiana grew.
