Passing a budget resolution for 2018 through the Senate will open a procedural door to a $1.5 trillion tax cut over 10 years. The resolution is expected to reach the Senate floor this week, although there are questions about whether Republicans have the 50 votes they need to pass it. Sens. Susan Collins (R-ME) said this weekend that she would vote for it and Lisa Murkowski (R-AK) is likely a “yes” as well, but Sen. Rand Paul (R-TN) is reportedly a likely “no” and John McCain (R-AZ) appears questionable. Now it looks like Sen. Thad Cochran (R-MI) won't be back in Washington this week to vote on the resolution due to health problems. The Hill says Cochran’s absence puts tax reform “on knife’s edge.”
