As I’m sure all astute Duck readers are aware, today marks a critical day in the US House and Senate – if no deal is struck today on a spending bill, the US government will shut down at one minute after midnight on Tuesday morning. The issue at the heart of the controversy: a series of amendments to the spending bill that concern the Affordable Care Act (so-called “Obamacare”). In general, House Republicans are in favor of the amendments; Senate Democrats are against the amendments. So, both sides are holding firm to their stance on the amendments in hopes that the other side caves in before tomorrow. What are the likely outcomes of this situation?
