AZ doesn’t have any voter fraud.
Neither does Alabama.
Sinema won because she busted her ass. She knocked on every door in Phoenix. Her opponent thought that simply having an (R) after her name would suffice.
Jones won because he ran against an opponent so loathsome that over 600,000 Trump voters stayed home.
No fraud required. Run unpalatable, uninspiring candidates, don't be surprised when they lose.
