At a crowded rally in downtown Austin, Beto O’Rourke ticked off his usual laundry list of campaign promises: stabilizing the power grid, rolling back the state’s new permitless carry law and expanding health care access.

But the El Paso Democrat got some of the loudest cheers of the night when he promised to legalize marijuana in Texas, something he said “most of us, regardless of party, actually agree on.”

“I’ve been warned that this may or may not be a popular thing to say in Austin, Texas,” O’Rourke said to the crowd gathered in Republic Square Park in December. “But when I am governor, we are going to legalize marijuana.”

The support is nothing new for the gubernatorial candidate. O’Rourke has championed legalization efforts throughout his political career, ever since his time as a member of the El Paso city council. He also nodded at the policy throughout his failed campaigns for U.S. Senate and for president.

But in his early run for governor, O’Rourke, who declined to be interviewed for this story, has repeatedly mentioned legalizing marijuana on the campaign trail across Texas. Advocates hope the increased attention will give momentum to legalization efforts in a state with some of the harshest penalties and highest arrest rates for marijuana possession.

O’Rourke’s advocacy around the issue dates back at least to his time on the El Paso City Council in 2009 when he pushed for a resolution calling on Congress to have “an honest, open national debate on ending the prohibition” of marijuana.

Despite unanimously passing the city council, then-Mayor John Cook vetoed the nonbinding measure. Cook got some help from then-U.S. Rep. Silvestre Reyes, who warned council members the city could lose federal funds if they continued with their effort.
