Arizona could have twin astronaut senators.
What Sinema has become is what’s particularly gross to me. She was on video back in 2010 stumping for the Affordable Care Act, calling out Senators like Joe Lieberman and taking them to task for refusing to change the filibuster rules to pass significant legislation; explaining how she and other Democrats were going to use the budget reconciliation process to get good work done. Very much seeming to care about keeping an open dialogue with working class voters.
Now she’s fucking off in Davos, wearing a sheep or whatever and opining about the national debt on a huge stage in front of global business elites. That’s the kind of shit she wants to do, when she’s not killing bill after bill and doing curtsies on the Senate floor. She’s become worse than Joe Lieberman, Max Baucus and those intransigent assholes she used to name and shame. >

She betrayed everything she claimed to believe in for money. >

How long before she sells out the LGBTQIA community too? 
If she hasn’t already >

In 30 minutes for 2 million?! >

I think you're severely overestimating how much a politician costs.
I'm guessing somewhere in the neighborhood of $50,000. >

3 paper clips and a subway coupon. >

Nah you're thinking of McCarthy. >

McCarthy pays other people to listen to him. >

At this point, she has 0 path to reelection. The absolute most she can do is spoil it for someone else.
If the Democrats had decided not to run a candidate, maybe she could have won as an independent. I doubt it, but at least it would have been possible. With a Democrat already publicly announcing, that's shot.
So, what does she want to do with the rest of her life? Does she want to spend it as a conservative pundit, or lobbyist? If so, she should run, and try to take votes from the Democratic candidate, and then get the best such deal she can get. If she'd prefer to work on the Democratic side, or even centrist for what that's worth, she needs to not run at all.
But in neither case is she ever going to hold a national public office again. >

What if she went Republican? >

Not enough Republicans would vote for her, as she was a Democrat. >

Depends on who the Republican primary candidate is.  Keli Ward, Joe Arpaio, or even Kari Lake?  There is a non-zero chance she wins.  Also, I think her approval rating is higher among Republicans than Democrats. >

If she ran as a Republican and won the primary, the Democrats would run a candidate. She would lose enough Republicans that she really couldn't beat the Democrat. >

When Kyrsten Sinema was at Davos high-fiving Joe Manchin over their mutual vow to protect the filibuster, she may have actually given Ruben Gallego a boost.
