Speaking of which, in the next few years, Iran is likely to proceed unimpeded toward becoming a nuclear power, despite all the UN's empty resolutions. In turn the Israelis, who have learned to take threats to their existence seriously, are just as likely to take military action to destroy or at least delay Mahmoud Ahmedinejhad's dangerous ambitions. Just as they destroyed Syria's nuclear installation not long ago. When that happens, whom would you rather have sitting in the Oval Office?

Is the best way to revive the economy to cut taxes for all or to raise them just for the rich? (As if the rich were too dense to find tax shelters for their income.) As a practical matter, can that be done? How expropriate capital without affecting labor? Can we really draw water from only the other fellow's side of the bucket? And how define The Rich anyway - those one tax bracket above ours?

But, hey, this is politics - not economics or equity - and specifically the politics of envy, which flourishes in inverse proportion to prosperity. Look for more of the same as times get meaner. Bad times are the health of bad ideas. And false choices.

Which candidate will settle for nothing less than victory on what he considers the central front in the war against terror, whether Iraq or Afghanistan? Which foresaw and fought for the adoption of a new and successful strategy in Iraq, and does that matter if it's Afghanistan that's the real central front? And how realistic is it to reduce American strategy to a choice between abandoning one or the other?

Which candidate has a strategy for the future, and which is more interested in finding scapegoats? Speaking of which, has George W. Bush - come to think, he's still president of the United States - ever done a single thing right in his life? Like preventing another major terrorist attack on these shores for the past seven years, or seeing the war in Iraq through to the cusp of victory despite many a terrible blunder, or ending Saddam Hussein's genocidal reign there, or giving his secretary of the Treasury and chairman of the Federal Reserve a green light to do whatever's necessary to stop the current economic slide - or are both presidential candidates so intent on separating themselves from an unpopular president that they dare not acknowledge all that?

Which candidate would risk saying a single unpopular thing in this campaign for no better reason than he believes it?

As this election grinds on, voters will have their own questions to pose. And they'll doubtless be as rhetorical as mine.

Rhetoric is one thing, reason another. There are times when John McCain seems to be running against an unpopular Democratic leadership in Congress, with its earmarks and toxic twins (Fannie Mae and Freddie Mac). There are other times when Barack Obama doesn't seem to be running against his opponent but against George W. Bush, who isn't on the ballot this year.

Logic has little to do with politics, especially in an election year, when winning tends to become the only goal. In the mounting urgency of a campaign, who's got time or energy to waste making sense?

Another presidential debate is over. Another awaits. So does History.
