Dare I say it but I rank President Calvin Coolidge just a tad higher than even President Ronald Reagan. In fact, Coolidge was rightly admired by Reagan.
As for the populist idiocy that you so aptly mention, I place William Jennings Bryan in the same circle of evil as Woodenhead Wilson and Franklin Diablo Roosevelt. What became the New Deal were largely the visions of the so-called "Great Commoner". To a large extent, I see Mike Huckabee as a 21st Century version of Bryan.
The Bryan and Huckabee comparison is well noted, and a tragic one. Both men recognized the depravities of the "we-are-all-pond-scum" viewpoint known as Darwinism, yet advocate the Leftist form of government which treats man like pond scum. Governor Brownback is another tragic character; he had a viewpoint of "pro-life, whole-life", but unfortunately did not realize that this viewpoint should not be applied to the illegal invaders.
