Can America actually pass a serious climate action plan? Democrats stunned Washington D.C. and climate activists last week by rolling out a compromise deal between the notoriously pro-fossil-fuel Senator Joe Manchin, Democrat of West Virginia, and the Democratic Senate Majority Leader Chuck Schumer. But they need every Democrat to vote in favor, and Sen. Kyrsten Sinema of Arizona has remained silent, refusing to say whether she supports the deal or not. She also, in the past, opposed one of its key components: Tightening the so-called “carried interest” tax loophole, which the mega-wealthy rely on to pay lower taxes on their income than those who earn a regular salary. @gregwalters_ reports:
