Nine Republicans have filed to run for retiring Rep. John Shadegg’s seat in the Republican-leaning area of northern Phoenix and its suburbs. One, former state Sen. Jim Waring, was among 35 current and former state legislators to endorse Sen. John McCain (R-Ariz.) over his challenger, former Rep. J.D. Hayworth (R-Ariz.) on Thursday.
Paradise Valley Mayor Vernon Parker (R) has also endorsed McCain, even though he and Hayworth share a major campaign supporter: Maricopa County Sheriff Joe Arpaio.
