The centrist Democratic senators from Arizona and West Virginia, once united on shaving down the cost of a party-line social spending bill that started at $3.5 trillion, are now going their own way in the final stretch of negotiations on a linchpin of President Joe Biden’s agenda.

Sure, they both dislike the House progressives’ decision to hold up their infrastructure bill — but when it comes to policy specifics, Kyrsten Sinema and Joe Manchin are now in different places…

Just a few days ago, Sinema sent her party scrambling with her opposition to raising tax rates on corporations and individuals. Still, she eventually agreed to a compromise that targeted high-income earners. And as of Tuesday afternoon, Sinema was on board with a deal on prescription drugs.

Fellow Democrats view her as accepting Biden’s framework, according to senators and aides, even if she hasn’t explicitly said so and is somewhat mysterious to many in her party. Manchin is another story.
