Will Trump be impeached and removed from office?

Step-by-Step Analysis

Historical Base Rate Context: The base rate for presidential impeachment AND conviction is 0% - no U.S. president has ever been removed from office through this process in 250+ years of history. All 4 impeachments (Johnson, Clinton, Trump 2019, Trump 2021) resulted in Senate acquittal. This creates an extremely high prior against conviction.

Current Political Environment (March 28, 2026):

1. Narrow Republican Control: GOP holds 218-214 House majority and 53-47 Senate majority
2. Active Crises: 4-week Iran military conflict, partial government shutdown, controversial executive orders
3. Public Opinion: ~60% disapproval on war/economy handling; 1M+ signatures for removal
4. Market Divergence: 70% probability of impeachment alone vs. 22% for impeachment AND conviction

Path to Impeachment:

• Current Republican House: Very unlikely to impeach (2-4% by June 2026, 12-14% by year-end)
• Post-Midterm Democratic House: Highly likely (84% probability Dems flip House in November 2026)
• Democrats need only net +4 seats with current political environment favoring them
• If Democrats win House in November 2026, impeachment becomes probable in 2027-2028

Path to Conviction (The Critical Bottleneck): This is where the market's 22% probability appears slightly optimistic:

1. Mathematical Challenge: Senate conviction requires 67 votes

   • Even if Democrats win Senate majority (challenging map, need +4 seats), they'd have ~51 senators
   • Would need 16 Republican senators to defect and vote to convict
   • Zero historical precedent for this level of cross-party conviction voting

2. Republican Defection Analysis:

   • Trump retains strong Republican base loyalty
   • Republican senators face primary challenges from Trump-aligned candidates
   • Even during Trump's two previous impeachments with serious charges, maximum Republican defection was 7 senators (2021 impeachment)
   • Would need 2-3x historical maximum defection rate

3. Precedent Weight: The complete absence of successful conviction in U.S. history is a powerful prior that should not be underweighted

Scenario Probability Assessment:

The market's 22% appears to be pricing in:

• High probability of Democratic House takeover (~84%)
• High probability of subsequent impeachment (~80-90% conditional on Democratic House)
• Combined probability of ~12-15% from that path
• Additional ~7-10% probability from extreme crisis scenarios or multiple attempts

My Adjustment: I estimate 18% probability, slightly below the 22% market consensus because:

1. Senate Math is Nearly Insurmountable: Requiring 16 Republican defections with zero historical precedent is extremely unlikely even in crisis scenarios
2. Time Decay: While there are ~3 years remaining, each failed attempt reduces political momentum
3. Base Rate Weight: Zero successful convictions in history should anchor estimates lower
4. War Rally Effects: Military conflicts often increase presidential support (rally-around-the-flag effect), though this can reverse with prolonged failures

Why Not Lower?

• Unprecedented combination of crises (war, shutdown, executive overreach)
• Long time horizon (until Jan 2029) allows multiple attempts
• 60% disapproval is historically severe
• Economic damage (oil >$100/barrel, equity sell-offs) could worsen significantly
• If war escalates catastrophically or economic crisis deepens to 2008-level severity, Republican political calculus could shift

Edge Assessment: Market at 22% vs. my estimate of 18% represents modest overpricing (~4 percentage points). This suggests a potential edge on the NO side, though not overwhelming. The difference largely stems from my view that the market may be underweighting the constitutional impossibility of achieving 67 Senate votes and overweighting the impact of current crises on Republican senators' voting behavior.

MODEST EDGE ON NO: My 18% estimate vs. market's 22% represents a 4 percentage point difference, suggesting the market is modestly overpricing the probability of conviction.

Rationale for Edge: The market appears to be overweighting the impact of current crises (Iran war, shutdown, 60% disapproval) and underweighting the constitutional near-impossibility of achieving 67 Senate votes. Even with catastrophic crisis escalation, requiring 16 Republican senators to defect has zero historical precedent - Trump's worst-case impeachment achieved only 7 Republican votes for conviction.

Trade Recommendation: WEAK NO BIAS - At 22%, there may be modest value betting NO, but the edge is not overwhelming. The 4-point difference could be explained by reasonable disagreement about tail-risk crisis scenarios. Key considerations:

• If you believe the Senate math is truly insurmountable regardless of crisis severity → Bet NO
• If you believe current crises could escalate to regime-breaking levels → Market price is fair or underpriced
• Risk/reward favors NO slightly, but not strongly enough for high-conviction sizing

Monitoring Triggers: Watch for Iran war resolution (reduces probability), economic data (unemployment, GDP), Republican senator public statements, and November 2026 midterm results. If Democrats win House decisively in November, short-term impeachment odds will spike but conviction odds should remain low absent extreme crisis escalation.
