To his credit, John McCain has invited Barack Obama to join him in a national “town hall” tour over the coming months, without the unneeded intrusion of celebrity journalists, network extravaganzas and all of their irrelevant impertinence. The Arizona Republican insists that he wants a serious debate over the competing ideas and visions of the two parties, rather than the usual petty focus on process issues and gotcha questions.
