John McCain and Barack Obama are the last official candidates in the presidential campaign. They're raising money today and talking about the economy. Hillary Clinton has "suspended" her effort and endorsed Obama, but nobody knows what role she'll play between now and November.

Can the "veteran" McCain advocate change and avoid looking like old news?
