The Washington Post reports that Arizona Senator Kyrsten Sinema signed on to the “Inflation Reduction Act”—which provides funding for climate change/health care. Her demand? She blocked taxes on the wealthiest and on corporations that pay nothing. Why is she a Democrat?

Sen. Kyrsten Sinema (D-Ariz.) said she would “move forward” on a revised version of Senate Democrats’ health care, climate and deficit-reduction package, after party leaders agreed to scale back some of their original tax proposals.
The new approach — along with other changes to the proposal known as the Inflation Reduction Act of 2022 — satisfied Sinema’s chief concerns and helped set in motion a plan to approve it as soon as this weekend.

In a statement, Sinema said Democrats had “agreed to remove” a key tax targeting wealthy investors and had made changes to a second provision that aims to impose a new minimum tax on corporations that currently pay nothing to the U.S. government. From here, Sinema said she would await a final review from the chamber’s parliamentarian — a critical step in the process that allows Democrats to move their spending bill — at which point she would “move forward.”
