The arts don’t often register even a blip on the national political radar screen these days, but that didn’t stop the American Arts Alliance from asking presidential candidates to sign a “Pledge for the Arts,” and to detail what their hypothetical administrations would do to promote and support America’s cultural scene. John Kerry was the first to sign, and he was followed this week by Wesley Clark, Howard Dean, Dennis Kucinich, and Joseph Lieberman. President Bush did not respond to the Alliance’s request, although one could assume that he intends for his new proposal to boost funding for the National Endowment for the Arts to speak for itself.
