HOUSING

I'D RATHER LOSE WITH A CLEAN HOUSE

Austin rents are up 38% since 2021 in 78704 alone. Repeal Texas's 1987 state preemption that bans local rent control. Cap rent hikes at 5% a year on buildings owned by anyone holding more than 25 units. Federal Section 8 expansion to a guarantee, not a lottery.

HEALTHCARE

MEDICARE FOR ALL. CO-SPONSOR DAY ONE.

I co-sponsor HR 3421 on January 3, 2027. Period. 1 in 5 Travis County adults under 65 are uninsured. We pay more for worse outcomes than every other rich country on earth. I have organized nurses for six years. I know which fight this is.

CLIMATE

GREEN NEW DEAL FOR PUBLIC HOUSING

HR 5185 retrofits every public-housing unit in America to zero-emission. Texas loses $5.2B a year to climate-disaster damage and Greg Abbott still won't say the words. I will. Federal weatherization dollars to Austin first. Decommission ERCOT.

ENDORSED.

"Carlos has been knocking doors in District 4 for six years. The first organizer I've seen run for federal office who actually built the list before he announced."

GREG CASAR

"When teachers walked out in 2023, Carlos showed up at 5 a.m. with coffee and a sign. We remember."

KEN ZARIFIS
President, Education Austin

"Most candidates show up to a tenant meeting once. Carlos has been at ours for three years running."
