Ulikely though it may seem,
given my posting history,* my above little contribution had a serious intent: I meant to emphasize the emotionality of the Baggers' politics, as against any kind of rationality. (Of course they don't have rational convictions. How could they? They don't read, they can hardly write, and they despise and resent intellectualism.) I think that these folks can be characterized most usefully as reactionaries rather than as right-wingers per se.
But the trouble with being a reactionary in America, i.e., the trouble with wanting to return to some earlier time, is that these still are the Good Old Days: American social institutions are remarkably backward for a developed country; old times here are not forgotten. Probably that's because America's wealth is so prodigious that we can afford to lag behind the times. (I'd argue that the country's immense wealth makes it possible for us to be more socially progressive; but that's just an aside.) Except for the Cold War (which I think they enjoyed, those of them old enough to recall it), these poor people have no history. Perhaps they have no real society.
So what can the Baggers hanker for? Like all nativists, they construct a fantasy past and then believe in it, but that doesn't get them very far if they can't persuade any large number of voters to believe with them. Hence their disproportionate anger and hatred, their virulence, their frustrated yelling. XBox and geni have them about right: the Baggers don't know what in the hell they stand for, so by God they're going to stamp and yell and cavort all the harder.
They're nothing new. I'm old enough to remember when Barry Goldwater ran for prez, and the same species of bellowing emotionalists were in your face back then -- hell, it may have been their greatest hour, as they understand greatness.
I wish I had the Googleness to find an old Feiffer political cartoon from those days. It was a dialogue between Lil' Empty and Bang-Bang Barry, and it summarized the incoherent nature of this type of politics better than all of my already too-plentiful words.
