Unfortunately this mentally unstable, egomaniac has 3 years of playing Senator left.
She's too into herself to realize how toxic she has become to both parties.
At this point, she's basically worthless as a candidate for Senate. I don't think she could come close to winning either primary, and would have a hard time getting enough signatures to run as an independent.
In Arizona, party members must vote for candidates from their party. Only independents are allowed to choose which party's primary they'll vote in.
Standing against Biden's agenda may be a huge ego trip for her, but it's political suicide.
