ST. PAUL (Reuters) - Republicans John McCain and Sarah Palin kicked off a two-month battle for the White House on Friday with a promise that "change is coming," a theme co-opted from their Democratic rivals.
McCain touted his credentials as a reformer and portrayed himself as the real agent of change in the race against Barack Obama as he accepted his party's presidential nomination in an arena filled with supporters waving blue "Country First" signs.
"I don't work for a party. I don't work for a special interest. I don't work for myself. I work for you," McCain said in a speech that included only passing criticisms of Obama after a four-day convention marked by scathing attacks on the Democrat.
