Sen. John McCain, taking a victory lap as the presumptive Republican nominee, happily poked fun at his only remaining opponent. Asked during an appearance on "The Daily Show" last week which of the two Democratic nominees he preferred to run against in the general election, McCain quipped, "Ron Paul." But Paul might get the last laugh during McCain's coronation at the party's convention in early September. McCain's nomination may be certain, but he finds himself pressured by different wings of the conservative movement -- from the libertarians and the anti-war activists, to social conservatives and evangelical voters.
