Sen. James Webb has been trying to nail McCain down on a revamped GI Bill that would fund education for veterans. But the closest McCain has come to a position is to say he needs to examine it more closely. Both Obama and Clinton support the bill, and it's fair to assume that neither senator has any more leisure time than McCain. If the point is that the Republican candidate is incapable of multitasking, that's something he might want to lick before he becomes president, a job in which, to paraphrase the White Queen from "Alice in Wonderland," a person is often asked to tackle six impossible things before breakfast. Or maybe it's just safer not to take a position than to take one, to try to be all things to all people by being nothing at all.

This is completely at odds with the patented McCain persona, the alleged guy who speaks his mind without fear or favor. His notorious irascibility is often mistaken for principled candor, but experience teaches that McCain's principles remain consistent now only when they appear to lead to the West Wing. Sadly, no one understands better the personal cost of such pandering. In 2000 he was asked about the Confederate battle flag, which flew from the capitol dome in South Carolina. McCain first called it a "symbol of racism and slavery," then backed off with a "clarification" that described it as a "symbol of heritage." Later he admitted, "I feared that if I answered honestly, I could not win the South Carolina primary. So I chose to compromise my principles."

He has done that over and over during this race. The Straight Talk Express is all over the road. There are those optimists who like to believe that once elected, McCain would again emerge as a small-government progressive who would set his own course. But it is the greatest of illusions to believe that a man will masquerade to win, then revert to his authentic self—after all, there is always another election coming. "Important principles may, and must be, inflexible," said Abraham Lincoln. Or maybe this says it best: "I wanted them to think me still an honest man, who simply had to cut a corner a little here and there so that I could go on to be an honest president." That's from McCain's 2002 memoir, but perhaps there's been a "clarification" issued since.
