She'll draw a liberal challenger who generates a lot of online buzz and raises a considerable amount of money, but Sinema still wins the primary by >40pts in the end.
She then goes on to lose the GE when Ron DeSantis defeats Kamala Harris in the first popular vote majority for the GOP since 2004 (AZ goes for DeSantis by >5pts)
This isn't a fan fiction site.
Why is Sinema some electoral juggernaut when she only won by 55k votes in about the most pro-Democrat midterm environment you could ask for?
In a scenario where Republicans win 2024 handily (which is well within the realm of possibility) she stands little sense of surviving.
