By all measures of American politics, this should be the moment Republicans cement an unstoppable governing majority. Charlie Cook of The Cook Political Report emails: "From the presidency, to Congress, governors and state legislatures, Republicans hold more offices than any time since the 1920s. ... This is the most favorable Senate map that either party has had in modern history, maybe ever. ... Things don’t get much better."
