Democratic presidential candidate Bernie Sanders addressed several national issues before a fervent crowd in Spokane Sunday.

The rally came just days before Washington and Idaho’s caucuses this week.

“I hope Saturday the people of Washington stand up proudly and help America start a political revolution,” he said just before ending his 45-minute speech to a excited crowd.

Thousands of people began lining up at the Spokane Convention Center hours before the event, some arriving as early as 7:30 a.m. The main room quickly reached capacity after the doors opened, and all other attendees were directed to overflow rooms or had to wait outside. Campaign officials counted close to 10,000 supporters that showed up by the night’s end.

Sanders spoke shortly to the crowds in the overflow rooms and outside before taking to the main stage. A campaign official said time was limited to reserve space at the convention center and that bigger spaces had already been reserved.

Spokane was the last of three rallies he did in the state, speaking in Seattle and Vancouver earlier that day.

Sanders focused on his two biggest opponents on the campaign trail.

He said Republican front runner Donald Trump lies too much and will not be president, and also criticized Trump’s involvement in the birther movement, which called for Obama to prove his U.S. citizenship.

He told the crowd Americans do not want a president “who insults Mexicans, who insults Muslims, who insults veterans, who insults women.”

Sanders also focused on democratic candidate Hillary Clinton and called on her to release the transcripts of her Wall Street speeches.

“One of the differences between I and Secretary Clinton is how we raise money,” he said, noting that he has no Super PACs and raises money independently.

Democracy is not about “billionaires buying elections,” Sanders said. “We will not allow this country to become an oligarch society.”

Sanders also discussed his usual topics of unequal distribution of wealth and global warming, which he said will heat the planet up 5 to 10 degrees by the end of the century if nothing is done.

“We have a moral responsibility to leave this planet in a way that is healthy and inhabitable for our children and their children,” he said.

He also covered the criminal justice system and said the U.S. incarnates more people than any other country in the world, especially minorities.

Sanders congratulated Seattle for raising its minimum wage to $15 an hour and promised to do the same for the rest of the country. He also said he would push for equal pay for women.

“We are not going to cut Social Security, we are going to expand Social Security,” he added.

He also delved into the issue of student loan debt.

“Why is it when young people do the right thing, they get $30,000 to $50,000 in debt?” he asked. “Why are we punishing people for getting an education?”

He added that people need an education now more than they did 50 years ago, especially to survive in the workforce.

Sanders promised to improve relations with Native Americans in the U.S. and discussed the poor conditions that many communities are living in today.

“We owe an enormous debt of gratitude to the first Americans,” he said. “We have learned so much from their way of life.”

The rally attracted several WSU students from the Pullman and Spokane campuses. Among them was fifth-year senior eastern religious studies major Bryce Park, who has also volunteered locally on Sanders’ campaign.

“It was a truly amazing experience,” he said. “The excitement and passion could be felt all daylong up and down the line.”

Park said Sanders’ discussion on Native Americans is what stood out the most to him and said it’s a more recent addition to the candidate’s speech.

Miralem Cusic, 32, a WSU alumnus and Spokane resident said he supports Sanders’ fight for universal health care and believes it’s a right for every citizen.

“No one should go broke because they’re sick,” he said.

Education was another important topic for this supporter. Cusic said he worked in the Office of Financial Aid while he was a student and saw many who were struggling to get by.

“I think everyone should have some access to basic college education,” he said.

Sydney Johnson, a first year political science and psychology major at WSU traveled from Pullman to the event.

“Bernie definitely filled the room with positive energy during his speech,” she said. “I feel privileged to have been able to be at the rally representing WSU and, of course, Senator Bernie Sanders.”

Idaho will hold its Democratic caucuses tomorrow. Washington Democrats caucuses will be on Saturday.
