Now it's John Thune who faces pressure points on the Trump budget

1. Death by energy: Sens. Lisa Murkowski (R-Alaska), John Curtis (R-Utah), Thom Tillis (R-N.C.) and Jerry Moran (R-Kan.) are demanding that leadership protect the Inflation Reduction Act's energy credits from getting cut.
2. Death by Medicaid: Murkowski and Sens. Susan Collins (R-Maine) and Josh Hawley (R-Mo.) voted on an amendment to protect Medicaid. They've made clear they won't vote for any cuts to benefits.
3. Death by spending: Conservative Sens. Mike Lee (R-Utah), Ron Johnson (R-Wis.) and Rick Scott (R-Fla.) frequently join Paul to raise alarms about the growing deficit.

What to watch: Trump's ask for the cap on the State and Local Tax (SALT) deduction to be raised will be another unpopular proposal with Senate Republicans, who are much less amenable to the idea than those in the House.

• Committees will now get to work on how exactly they want to fund border security and the military — and where they want to take a hatchet to current government spending.

The bottom line: It's not impossible to keep everyone happy on the specifics of Trump's "one, big beautiful bill," but it will be a headache.

• Adding to the degree of difficulty, Thune and Johnson have to get this bill passed before the debt ceiling "x-date" in August or September or risk a global financial crisis.
