McSally and SInema portrayed themselves as dramatically different, said Aaron Kall, director of debate at the University of Michigan.McSally, 52, was aggressive in trying to press her points and alternated between relatable and combative Sinema, 42 deliberately strike a measured tone.

The debate's most memorable moment came when McSally took control of the questioning as the event sped toward closing statements, during a question about climate change. Realizing she would not have time to highlight what she sees as her greatest strengthMcSally sped up the pace of her speaking and tried to use her final moments to attack. "We have to talk about our military," McSally said, her hands waving, her voice rising. "We have to talk about our veterans."Kall, citing McSally's yelling over the moderators and her gesturing, said, "In real time, McSally was realizing that this kind of makeover or transformation, or independent streak ... may be working in relating to voters, especially low-information voters who may be tuning in for the first time."Sinema struck a tone similar to that of a parent expressing disappointment in a child."Martha has chosen to run a campaign like the one you’re seeing right now where she’s engaging in ridiculous attacks and smearing my campaign. And she’s just trying to cut, cut, cut, and not show the full picture.” Sinema's refusal to look at McSally showed she was not going "to take the bait(like Liz Warrent)."Sinema's body language may have sent a cue to voters that she views McSally and her campaign as "a campaign in the gutter, willing to do anything to win." Kall compared Sinema's approach to the moment like a boxer: "Just let the bell ring and the time expire." Arizona Central
