Scorching temperatures hitting the Bay Area sent at least one Bernie Sanders supporter to the hospital on Friday.
The Democratic presidential candidate's lively and large rallies were much smaller on Friday due to the intense heat.
In Fairfield, a rally at the Solano Community College prompted Sanders to thanks supporters for toughening out the weather.
"I want to thank all you crazy people for coming out on a day like today," Sanders said, which was met with cheers from the crowd.
People waited for hours, lining up in the sunshine as early as 5:30 a.m. But by the time Sanders took stage at 2:45 p.m., the burn of Mother Nature proved too much for some. At least two people passed out and were taken away by paramedics.
"A few hours in the heat, but California is in a drought so we're used to this," one Sanders supporter said of the intense weather. "Have to feel the Bern, so here we are."
Attendees did what they could to keep from overheating as Sanders outlined the differences between himself and Hillary Clinton. He also blasted presumptive GOP nominee Donald Trump for his views on the drought and global warming.
"Donald Trump does not have a clue what he's talking about," Sanders said.
With some polls showing Sanders closing the gap with Hillary Clinton, he urged supporters to help him get out the vote on Tuesday.
"If there's a large voter turnout on Tuesday, we're going to win California and win it big."
Despite Friday's hot weather, supporters said they would brave the scorching temperatures again to feel the Bern.
After visiting Fairfield, Sanders stopped by the University of California, Berkeley for for a press-only meeting to discuss economic and trade issues.
