State primaries were held Tuesday in Alaska, Arizona, Florida, Oklahoma and Vermont. In Arizona, Republican Senator John McCain of Arizona easily defeated the tea party-backed candidate J.D. Hayworth to seek a fifth term.

Senator John McCain: “I promise you — I take nothing for granted — I’ll fight with every ounce of strength and conviction I possess to make the case for my continued service in the Senate and the policies and principles I will advocate and defend if I’m fortunate enough to be re-elected.”

In another Arizona vote, Ben Quayle, the son of former Vice President Dan Quayle, won the Republican nomination to seek a House seat in a Phoenix district. Quayle had made headlines during the campaign for running an ad calling President Obama the worst president in US history. In Alaska, Republican Senator Lisa Murkowski is trailing tea party-backed opponent Joe Miller with over half of precincts reporting.
