The Democratic candidate for president spoke for nearly an hour, focusing on the central themes of his campaign, including income inequality, money in politics,and growing wages. “For the last 40 years the great middle class of this country—once the envy of the world—has been disappearing,” Sanders said. "We need to stand together to make a political revolution where we create an America that works for all of us,” he continued. “Enough is enough—the billionaires are not going to have it, it’s our country. Let’s create that nation!” Citing figures from the Phoenix Convention Center, Sanders’ campaign spokesman said 11,347 people attended the rally.
