The first president whose campaign was his qualification for office continues to campaign. And he is overexposed. His schedulers should remember what a contemporary said of Thomas Babington Macaulay, a prodigiously articulate but oppressively constant talker: "He has occasional flashes of silence that make his conversation perfectly delightful." One afternoon last week, cable news viewers saw, at the top of their screens, the president launching yet another magnificent intention -- the disassembly and rearrangement of the 17 percent of the economy that is health care. The bottom of their screens showed the Dow plunging 281 points. Surely the top of the screen partially explained the bottom.
