Our nemesis is time, against which we have a single ally, memory, and even it betrays us.

Pat Buchanan has emerged as the prophet and forerunner of a real economic nationalism on the right, and Donald Trump is now its tribune. This is not movement ideology which is all about limited government, the power of free markets and also internationally - globalism.

Donald Trump descends in a very powerful way from longstanding tenets of American conservatism, they're just not the movement conservatism we associate with Reagan.

Donald Trump enters office with historically low approval ratings, that's where the battle could get fought. If the country turns against him, his Republican adversaries could feel emboldened.

The Republican - conservative Republican answer has always been when we lose it's because we're not ideological enough. If they lose midterm elections, that's why. If Obama defeats McCain and then Mitt Romney, it's because those two Republican candidates were not ideological enough.

Donald Trump very clearly said America first. That is a traditional right wing, but also very isolationist. That takes us back to the era of the 1920s, when there were immigration restrictions, and also to the isolationism before World War II.
