No, Mesa was Hayworth...in fact the border between Flake and Hayworth was Elliot Road in Chandler. I’m pretty sure Flake had nothing at all in Mesa.
I agree with you...Sinema is a bit “out there” for most of us, but don’t underestimate the lunacy of Tempe voters who have a high turnout. I hope she keeps promising to take her progressive values to DC, as she said in her primary commercials.
I looked it up, and it appears that I was correct. Heavily Mormon Mesa (plus Chandler and areas to the east) was in the AZ-06 (held by Mormon Jeff Flake, who resides in Mesa):

Meanwhile, the Hayworth/Mitchell/Schweiker AZ-05 took in Tempe and Scottdale, some areas directly south, and lots of Maricopa County to the north and northeast (but not Mesa):

In any event, the new AZ-09 only gave Obama 51% in 2008 and was just about evenly split between Bush and Kerry in 2004 (someone posted that Bush had narrowly carried it, and that could well be correct), so Mayor Parker has a real chance of beating Sinema.
