We have strong disagreements with all the Republicans running for president. The leading candidates have no plan for getting American troops out of Iraq. They are too wedded to discredited economic theories and unwilling even now to break with the legacy of President Bush. We disagree with them strongly on what makes a good Supreme Court justice.

Still, there is a choice to be made, and it is an easy one. Senator John McCain of Arizona is the only Republican who promises to end the George Bush style of governing from and on behalf of a small, angry fringe. With a record of working across the aisle to develop sound bipartisan legislation, he would offer a choice to a broader range of Americans than the rest of the Republican field.

We have shuddered at Mr. McCain’s occasional, tactical pander to the right because he has demonstrated that he has the character to stand on principle. He was an early advocate for battling global warming and risked his presidential bid to uphold fundamental American values in the immigration debate. A genuine war hero among Republicans who proclaim their zeal to be commander in chief, Mr. McCain argues passionately that a country’s treatment of prisoners in the worst of times says a great deal about its character.

Why, as a New York-based paper, are we not backing Rudolph Giuliani? Why not choose the man we endorsed for re-election in 1997 after a first term in which he showed that a dirty, dangerous, supposedly ungovernable city could become clean, safe and orderly? What about the man who stood fast on Sept. 11, when others, including President Bush, went AWOL?
