Did McCain's defeat mean anything?

George Will, getting it exactly right:

Although John McCain’s loss was not as numerically stunning as the 1964 defeat of Barry Goldwater, who won 16 fewer states and 122 fewer electoral votes than McCain seems to have won as of this writing, Tuesday’s trouncing was more dispiriting for conservatives. Goldwater’s loss was constructive; it invigorated his party by reorienting it ideologically. McCain’s loss was sterile, containing no seeds of intellectual rebirth.
