PHOENIX (AP) - In Arizona's brand-new 9th Congressional District, three Democrats and seven Republicans are vying to win the upcoming primary so they can move on to what could turn out to be a nasty fight for the seat.
The 9th District was created because of Arizona's population growth and through a controversial redistricting process.
It's contained entirely in metro Phoenix and includes much of Tempe and smaller sections of Phoenix, Scottsdale, Paradise Valley, Mesa and Chandler.
At 34.6 percent of the roughly 362,000 voters in the district, more are registered as independents than either Republicans or Democrats.
About 34 percent are listed as Republicans and 30 percent are listed as Democrats.
