FOX News projects that Senator John McCain will win his fifth, and, he says final, term in Arizona. McCain, 74, survived a grueling primary challenge, but will cruise to victory over attorney Rodney Glassman. Another longtime Republican Senator, Chuck Grassley of Iowa, is also projected to win. Democrats once touted the chances of former state Attorney General Roxanne Conlin, but this one was no contest as Grassley goes to a sixth term.

Also in Iowa, Republican Terry Branstad is heading back to the governor's mansion. FOX News now projects that incumbent Democrat Chet Culver will be defeated in the Hawkeye State.
