“President Bush made only one reference to Hollywood in his acceptance speech at the Republican National Convention on Thursday night, and it was almost in passing, but he hit the moviemaking community where it lives.” In one sense, it’s merely a case of one candidate taking advantage of an easy target set up by his opponent. But the Kerry/Hollywood flap has proved to have legs as a political story, and may serve to highlight a larger clash of values, between what the GOP sees as the conservative “heartland” and what Democrats see as the star power of the mainly liberal world of big entertainment.
