At first sight, the decision to insist on keeping a provision that benefits some of America’s wealthiest people seems a far cry from the concerns of voters in Sinema’s southwestern home state of Arizona.

Ya she was awful. She won her seat as an openly LGBTQ+ Democratic candidate. You’d at least figure she’d vote in line with the party. But with a closely divided Congress, every vote counts. Remember the ACA repeal vote was foiled by one no vote from John McCain.
So it was pretty obvious when she started to vote against the party, in favor of special interests and not people, that she was getting something from being one of the holdouts. I think she switched to Independent toward the end of her career there. Now she’s pushing AI data centers in AZ because she just goes where the money is.
