Guess it takes a maverick to not believe any of the polls. Asked on Fox News Sunday if Sarah Palin could beat President Obama if she decided to run, McCain exclaimed, "Of course she can." McCain praised his former running mate for inspiring "great passion, particularly among the Republican faithful." He blamed the media for discrediting her reputation, saying he's never seen someone be "mercilessly attacked" as much as Palin in recent years. Palin’s bus tour kicked off Sunday with a stop on the Rolling Thunder motorcycle rally in Arlington, Virginia.
