AP 'factchecks' Bob Casey ...

SEN. ROBERT CASEY JR.: "John McCain calls himself a maverick, but he votes with George Bush 90 percent of the time. That's not a maverick. That's a sidekick."

THE FACTS: McCain voted with President Bush 90 percent of the time from January 20, 2001, to when Congress left Washington on its annual August recess, according to a study by Congressional Quarterly. But McCain wasn't always a staunch Bush backer. In 2005, his support for Bush's position on legislation reached a low of 77 percent; last year, when he launched his latest bid for the GOP presidential nomination, he voted with Bush 95 percent of the time.
