The House voted to allow year-round, nationwide sales of E15 gasoline — a blend 50% richer in ethanol than the standard E10 pump grade. The play is straightforward: corn-state members from both parties needed a demand floor as domestic corn supplies swell, and this delivers one. Watch the Senate: farm-bloc leverage is real, but oil-refinery lobbyists have killed E15 expansions before, and the reconciliation calendar gives leadership a reason to keep this moving fast or drop it entirely.
