Key Policy Positions

Universal Care Plus Act

Brown proposes a national firearm registry as a centerpiece of gun violence prevention — a more aggressive proposal than most Democratic primary candidates, who generally focus on background checks and red flag laws rather than comprehensive registration.

Immigration Reform

Supports immigration reform, though specific policy details were not detailed in publicly available sources reviewed as of February 2026.
