Several reasons.
1. He began early with a terrible blitz of negative advertising against Kelli, outspending her 10:1. This time, she has money and Flakey does not.
2. McTurd was given one last chance by AZ and I personally know three people who voted for him who say if they could do it over they’d vote for her. But he lied just enough.
3. McTurd, unlike Flakey, has a very strong “retirement” vote that still remembers him from Vietnam and as a conservative Congressman, not as the nutjob he has become.
If Kelli Ward were to win the primary, she will have her hands full with Kyrstyn Sinema (or however the hell she spells her name). She is very slick and makes bald-faced lies directly to women, who buy her crap lock, stock and abortion mill. Pelosi and that crowd have been grooming Semena, "the Prada Socialist" (her words, not mine), for years and her time is almost nigh. She is frightening...pure evil.
The other challenger is likely Phoenix mayor Greg Stanton. I call Stanton "The Muppet" because he flops his head up and down while he talks, exactly like the Muppets' Ralph the Dog. He is an idiot. A doofus, a dork, a stoner who has spent way to much "me" time with the bong. Which is why I am convinced the DNC will go with Cinnamon.
