TV Rules

Senator John McCain of Arizona announced his decision to run for president in The Late Show With David Letterman. The list of politicians announcing their candidacy in talk shows seems inevitably to grow. Arnold Shcwarzenegger, now governor of California, announced that he was running for the governor of California in Jay Leno's show, in California.

In today's era of television, where pop appeal matters, the road to the White House no longer goes through only Larry King.
