"Barry Goldwater and Nelson Rockefeller got into an argument and George Wallace won."
Jonathan Rauch looks at the state of the GOP. He's not trying to call contemporary Republicans racist by connecting them to Wallace:
[L]ike Wallace and his supporters 40 years ago, today's conservative populists are long on anger and short on coherence. For Wallace, small-government rhetoric was a trope, not a workable agenda. The same is true of his Republican heirs today, who insist that spending cuts alone, without tax increases, will restore fiscal balance but who have not proposed anywhere near enough spending cuts, primarily because they can't.
The meat of his article:
I am saying three things.
First, with the important exception of race, not one of Wallace's central themes, from his bristling nationalism and his court-bashing to his anti-intellectualism and his aggressive provincialism, would seem out of place at any major Republican gathering today.
Second, and again leaving race aside, any Republican politician who publicly renounced the Wallace playbook would be finished as a national leader.
Third, by becoming George Wallace's party, the GOP is abandoning rather than embracing conservatism, and it is thereby mortgaging both its integrity and its political future. Wallaceism was not sufficiently mainstream or coherent to sustain a national party in 1968, and the same is true today.
Conservatism is wary of extremism and rage and anti-intellectualism, of demagoguery and incoherent revolutionary rhetoric. Wallace was a right-wing populist, not a conservative. The rise of his brand of pseudo-conservatism in Republican circles should alarm anyone who cares about the genuine article.
