Regardless of what the polls say, it's not clear who is going to win the presidential race. But it is clear who is going to lose: George W. Bush. If this contest proves anything, it's that the electorate is sick of him and eager for someone very different.

They might even prefer the candidate they elected in 2000. The one who promised to be "a uniter, not a divider." Who said he would "call for responsibility and try to live it as well." Who said the United States should be "a humble nation." Who faulted Al Gore for plotting to enlarge the government.

That candidate soon became famous for exploiting divisions, refusing to hold himself or his subordinates accountable, letting expenditures soar and making America synonymous with arrogance in much of the world. Whatever Americans hoped Bush would provide, it's safe to say that an open-ended war, an assault on the Constitution and an economic panic were not among them.

Americans may decide to replace him with another Republican, but if John McCain emerges victorious, it will be a tribute to his efforts to convince voters that he and Bush have barely met. Sometimes he sounds like he's running against Bush rather than Barack Obama.

One of his TV ads asked, "The last eight years haven't worked very well, have they?" An earlier one charged, "We're worse off than we were four years ago." At a recent rally, for anyone who missed the subliminal message, he thundered, "I'm not George Bush!"

Any GOP nominee might do the same. But not just anyone could offer attributes that contrast so markedly with Bush's. The president arrived as a foreign policy novice, with only six years in public office and a history of uninterest in what lay beyond our borders. Bush referred to the people of Greece as "Grecians," and in a 2000 radio interview, couldn't name the president of Pakistan.

Those are not the sort of mistakes the Arizona senator would make. McCain has traveled the world and made it his responsibility to inform himself about it, from multiple visits to Iraq to regular appearances at the annual Munich Conference on Security Policy, where defense officials from dozens of countries gather to discuss matters of war and peace.

Last spring, his aides were able to name 69 countries he has visited, which they said was not a complete list. One of the most arresting moments of the campaign came in the second debate, when he said, "I've been to Waziristan" -- winning the prize for the most unlikely boast ever heard in a U.S. election.

He was also a combat pilot and a prisoner of war, both of which tend to confirm one's seriousness in a way that Bush's unimpressive stint in the Air National Guard didn't.
