Bernie Sanders is making one last push for a prescription drug pricing ballot measure in California on Monday, just before Election Day.

Sanders has been campaigning for Prop. 61 for more than a month and has already appeared in two rallies in California -- one in San Francisco and another in Los Angeles.

The former Democratic candidate for president will return to Sacramento on Monday for a rally from 1:30 p.m. to 3 p.m. on the West Steps of the state Capitol. The last time Sanders was in the capital city, he was rallying supporters for his presidential campaign.

Before hitting Sacramento, he'll also be returning to Los Angeles to rally in Pershing Square from 10 a.m. to 12 p.m. Organizers have created Facebook events with details here.

The ballot measure has become the costliest campaign in California. It would require state agencies to purchase prescription drugs at the lowest price paid by the Department of Veterans Affairs.

After making a huge progressive splash on the presidential campaign trail, and considering his experience as chair of the Senate Veterans' Affairs Committee, spokesperson for the Prop. 61 campaign Roger Salazar said Sanders is the perfect surrogate for the measure.

"Bernie has been very gracious and outspoken against the greed of the pharmaceutical industry and he's been a longtime advocate for lower drug prices," Salazar said. "I just think Bernie excites a lot of people and he has a lot of credibility when it comes to talking about corporate greed."
