Bloomberg – March 9, 2026
Host: Joe Mathieu
Guest: Nathan Dean, Senior Policy Analyst, Bloomberg Intelligence

Episode Overview

This episode features Bloomberg Intelligence’s Nathan Dean giving a rapid-fire, well-informed rundown of Washington’s top policy stories and legislative catalysts for the week. Key topics include the GOP House retreat in Miami, President Trump’s hardline stance on the SAVE Act, the complex path for any new reconciliation bill, evolving Iran defense supplemental funding discussions, the looming Department of Homeland Security (DHS) shutdown, the Senate’s housing bill, and an early look at midterm election probabilities.

Dean’s insights are tailored to investors, lobbyists, and policy-watchers aiming to anticipate market-moving decisions in Congress and the White House.

Key Discussion Points & Insights

1. House GOP Retreat & Trump’s “SAVE Act” Demand

[01:01 – 06:30]

• House Republicans gather in Miami while the Senate remains active in D.C.
• President Trump declared via Truth Social he would not sign any legislation unless the SAVE Act—focused on citizenship requirements and voting—was passed.
  • Trump also introduced additional provisions and linked the SAVE Act to all legislative progress.
• The SAVE Act is unlikely to clear the Senate due to the filibuster’s 60-vote requirement.

“President Trump over the weekend said, look, I'm not going to sign any type of legislation until the SAVE Act is dealt with.”
— Nathan Dean (03:15)

• Utah’s Senator Mike Lee is pushing for a “talking filibuster” instead of abolishing the filibuster, but Majority Leader John Thune opposes any changes that could let Democrats “junk up the rest of the calendar.”
• The legislative threat is real: holding out for the SAVE Act would also block confirmations (e.g., for DHS Secretary or Federal Reserve Chair) and major bills like the crypto bill.

“…if President Trump actually stays true to this, it effectively blocks the calendar and it really slows things down.”
— Nathan Dean (05:20)

• Dean recalls bipartisan opposition to killing the filibuster (“…why Senator Sinema and Senator Manchin…were very supportive of [keeping] the filibuster…”).

2. Prospects for a New Reconciliation Bill

[06:30 – 09:50]

• Speaker Johnson is entertaining a new reconciliation package, with only a 20% chance of passage by Dean’s estimate.
• Challenges:
  • One-seat GOP margin in the House makes uniting “deficit hawks” and moderates difficult.
  • Attempts at a wide bill risk becoming a “massive trillion dollar spending package” dotted with attachments (defense spending, Obamacare tweaks, tariffs, Medicare cuts).
  • Political reality: Election season makes any major cuts radioactive.
• Narrow, targeted reconciliation (e.g., just Iran defense spending) is more feasible—but smaller bills attract attempts to expand their content.

“Every single thing gets added to it and you have a massive bill that you have to find offsets for... it's going to be extremely difficult.”
— Nathan Dean (08:10)

• House Budget Chair Jodey Arrington wants a big bill, but House Ways and Means Chair Jason Smith objects: lack of consensus persists.

3. Iran Defense Supplemental Package

[09:50 – 12:40]

• Still awaiting the White House’s precise “ask” for additional defense funding for Iran-related initiatives.
  • Pentagon numbers floated are as high as $50B–$150B.
• Dean highlights the lobbying frenzy that will erupt once the bill surfaces, with various interest groups working to attach unrelated provisions (e.g. $15B in farm aid from Ag Committee; broader push for $50B).
• Dean predicts the farm aid attachment “gets done this year” due to current farm sector struggles and recent Trump administration support.

“We've already heard folks over at the House Ag Committee saying about attaching $15 billion in aid to the Iran defense supplemental bill… I think it gets done.”
— Nathan Dean (11:45)

• Main takeaway: Iran supplemental is likely but will be a magnet for legislative “add-ons.”

4. DHS Shutdown and TSA “Sickouts”

[12:40 – 14:25]

• Signs of strain: TSA sickouts are building, with several-hour lines reported at major airports.
• Historical precedent: TSA sickouts ended the 2018–19 shutdown after escalating delays.
• No substantial movement on “DHS tactics” negotiations, but Dean expects a resolution mid-to-late next week.
• Practical advice for travelers: Arrive early; Global Entry remains closed; PreCheck is open.

“If you were flying through Houston Hobby Airport, you may have seen the lines that the TSA sickouts have begun… the TSA line was actually longer than the flight from Newark to D.C.”
— Nathan Dean (13:30)

5. Senate Housing Bill

[14:25 – 16:15]

• The Senate is set to pass a bill to bar corporations from investing in single-family homes (applies to funds owning >350 homes).
• Bipartisanship: Bill is sponsored by both Tim Scott (R) and Elizabeth Warren (D), passing cloture 84–6.
• Contains a ban on central bank digital currency (CBDC) through 2030.
• Anticipated House pushback, but Dean expects eventual passage with negotiable tweaks.
• Passage would clear the way for the next legislative priorities: the crypto bill and closure of the DHS funding gap.

“If you have Tim Scott on the same side of Elizabeth Warren, this is a pretty bipartisan bill... I expect some more hiccups, the House saying, look, we don't like this, we don't like this… Ultimately think this bill passes.”
— Nathan Dean (15:45)

6. Congressional Calendar & Legislative Outlook

[16:15 – 17:15]

• Only a handful of substantive bills are likely to pass before the midterms—possibly just housing, crypto, and a DHS resolution.
• This packed schedule leads to a surge in attempts to “attach” policy riders to must-pass legislation.

7. 2026 Midterm Election Preview – Senate & House Control

[17:15 – 20:00]

• Senate: Prediction markets give Republicans a slight edge to retain control (polling at ~52–55%).
  • Key races:
    • Georgia – High probability Ossoff holds (80%)
    • Maine – Collins in trouble; Dems at 71%
    • Michigan – Dems favored (81%)
    • North Carolina – Dems strong due to Governor Cooper (80%+)
    • Alaska – True toss-up; “the race to watch.”
    • Ohio, Texas, Minnesota, Florida – Mostly favor the incumbent party, with Texas not expected to flip despite headlines.
• House: Markets give Democrats an 84% chance to retake the majority.
• Dean’s rule: “US politics … never stays to the center. It always goes left, right, left, right…”—implying a House flip is probable after a presidential cycle.

“If the Democrats do take the House, it's only going to be by, I would imagine, 15 to 20 seats.”
— Nathan Dean (18:20)

8. Wildcard: Iran War Ceasefire Prediction Market

[20:00]

• Kalshi contract: “Will US-Iranian ceasefire occur by April 30, 2026?”
  • Previous week: 65% chance
  • Now: 46% and falling
• Implication: Market confidence in a near-term Iran resolution is fading.

Notable Quotes & Memorable Moments

• On legislative gridlock:
  “If President Trump actually stays true to this, it effectively blocks the calendar and slows things down.” [05:20]
• On legislative ‘Christmas tree’ bills:
  “If you have a bill that goes out there and says...we’re going to have increased defense spending, some Obamacare changes, tariffs... every single thing gets added to it and you have a massive bill.” [08:10]
• On midterms:
  “Think of US politics as like a car driving down the street with, you know, guardrails on both sides. It never stays to the center. It always goes left, right, left, right.” [18:05]
• On the odds of an Iran ceasefire:
  “Last week it was at a 65% chance…the conflict be over by April 30. Right now it’s at 46% and it’s dropping.” [20:05]

Takeaway

This episode delivers a comprehensive, timely snapshot of Washington’s fraught policy landscape in March 2026, highlighting how political brinksmanship, election-year caution, and complex legislative mechanics intersect to shape the week’s—and possibly the quarter’s—agenda. Legislative movement on defense, housing, and crypto are possible, but politics and the calendar are rapidly running out. Expect a choppy, unpredictable spring, with most major decisions at high risk of derailing or being weighed down by amendments and last-minute deals.
