Underdog Democrat Rodney Glassman posted a four-minute Web video Monday in which he sings his criticism of Republican incumbent John McCain in a takeoff of the Lynyrd Skynyrd classic "Sweet Home Alabama."

Dick and Peg Powell, retired teachers from Tucson, came to see U.S. Rep. Gabrielle Giffords debate the issues with Republican challenger Jesse Kelly. What they saw, instead, was a debate sprinkled with a lot of sniping from the two candidates, and even more booing and heckling from the audience.
