The new Tempe-based 9th District would be a competitive race for both parties. While a host of locals on both sides are sure to take a long look at the contest, the Arizona Republic notes that one ideal candidate for Democrats could be former Democratic Rep. Harry Mitchell. His former chief of staff slyly tweeted on Monday, "Harry Mitchell for Congress? Don't rule it out folks." The map also shores up Democrat Rep. Gabrielle Giffords' Tucson district, which would be numbered the 2nd District. President Obama narrowly won this redrawn district, taking around 50 percent. Giffords, who's still recovering from near-fatal January assassination attempt, hasn't decided yet whether she'll run for reelection, but if she does, it's hard to imagine Republicans contesting the seat. But if she doesn't run or seeks higher office later, it could become competitive. Democratic Rep. Ed Pastor's newly-numbered 7th District would become the most Democratic in the state. And after a close race in 2010, Democratic Rep. Raul Grijalva would see his now-3rd District also get slightly safer by picking up more Hispanic areas. Republican Trent Franks, who would be in the 8th District, is still in a solidly GOP seat. And while Rep. Jeff Flake, R-Ariz., is vacating his Mesa-based seat, now labeled the 5th District, to run for Senate. One of the several Republicans who have already lined up to replace him will be his all-but-certain successor.
