What Vance is arguing

Vance’s argument follows a common Republican narrative:

Joe Biden left the economy in bad shape (high inflation, high energy costs).

Policies under Donald Trump—especially expanding domestic oil and gas production—are supposedly helping push prices down now.

Therefore, current gas prices are lower than they would otherwise be because of Trump’s policies.

He and other Republicans frequently argue that more drilling, deregulation, and domestic production lower energy costs.

What actually affects gas prices

Economists generally say U.S. presidents have limited direct control over gasoline prices, because they depend mostly on:

Global crude oil prices

OPEC+ production decisions

Wars or geopolitical shocks

Refining capacity and supply chains

Seasonal demand

For example, in 2026 prices rose sharply due to conflict involving Iran, which pushed oil above $100 per barrel and caused U.S. gasoline to jump to around $3.50–$3.60 per gallon.

That kind of change happens regardless of which president is in office because it’s tied to global oil markets.

Did Trump policies lower gas prices?

It’s complicated:

Arguments supporters make

Expanding drilling and pipelines can increase supply long-term.

Expectations of higher future production can influence markets.

Arguments critics make

U.S. oil production had already reached record highs during Biden’s presidency.

Short-term gas prices mostly track global oil prices, not U.S. policy shifts.

Wars or supply disruptions can overwhelm any domestic policy effect.

✅ Bottom line:

Vance’s statement is a political interpretation, not a widely accepted economic conclusion.

Gas prices today are influenced much more by global oil markets and geopolitical events than by a single president’s policies.

Policies can affect prices over the long term, but they rarely explain short-term price levels.
