Democratic Sen. Mark Kelly of Arizona has won re-election, overcoming a challenge from Blake Masters, a 2020 election denier backed by former President Donald Trump, NBC News projects.Most polling leading up to Election Day showed Kelly with a consistent but increasingly narrow lead over Masters, who was running his first political campaign ... and it showed.But Masters couldn’t master basic political communication, as evidenced by his attempts to waffle on his proposal to privatize Social Security and his wiping of his most extreme views on abortion from his campaign website.Big money Republicans cut back on donating to his campaign on multiple occasions, showing a loss of faith in him just months out from the campaign.But Masters carried himself with arrogance that seemed to rub voters the wrong way, and Kelly capitalized on that haughtiness."
