Of the remarkable things we have learned this election year, the most significant is that the current Republican Party is unfit to lead the country. It has failed the greatest test a political leader or party can face, and failed spectacularly. It has abandoned its principles out of a combination of cowardice and opportunism. It has worked to place in the White House the most dangerous threat to U.S. democracy since the Civil War. And perhaps just as revealing, it has in the process engineered its own suicide. Not only has the party refused to save the country, but also it has proved too helpless, too incompetent and too craven even to save itself.
