Arizona primary day! Hooray!

IT'S PRIMARY ELECTION DAY in Arizona and for this occasion we can all be grateful. The senatorial race has been something awful, even witnessed from afar. Sen John McCain has increasingly seemed as disoriented as a sparrow in a windstorm. The dispatches from the front in that overheated sandbox assure us that McCain will win the Republican nomination against an opponent who is even less well-adjusted to reality than the former GOP presidential candidate. Perhaps the senator will now find time to return to earth.
