RECREATING REAGAN: Is the spirit of Reagan alive — if only on life support — in GOP circles? Even so much as an echo would be nice to hear at a time when the Republicans at both ends of Pennsylvania Avenue seem to have settled on liberal-lite. Meanwhile, in Sacramento: uanble to beat 'em, Arnold has pretty much decided to join 'em. No big surprise. For one thing, California's become a moderate-to-left state. Arnold's instincts are split: In his heart he's a Milton Friedman conservative/libertarian. But he's also used to big box office results. He likes being liked and he wants to keep his job next year.
