The 2016 presidential campaign of Bernie Sanders, the junior United States Senator and former Representative from Vermont, began with an informal announcement on April 30, 2015, and a formal announcement that he planned to seek the Democratic Party's nomination for President of the United States on May 26, 2015, in Burlington, Vermont. Sanders had been considered a potential candidate for president since at least September 2014. Though he had previously run as an independent, he routinely caucused with the Democratic Party, as many of his views align with Democrats. Running as a Democrat made it easier to participate in debates and get his name on state ballots. Sanders focused on income and wealth inequality, which he argued is eroding the American middle class, and on campaign finance reform. Unlike most other major presidential candidates, Sanders eschewed an unlimited super PAC, instead choosing to receive most of his funding from direct individual campaign donations. In September 2015, The New York Times reported that the campaign had received one million individual donations, becoming the first in 2015 to reach that threshold. Sanders raised $20,000,000 in the month of January 2016, $5,000,000 more than Clinton during the same time period, with an average donation of $27. Sanders frequently mentioned this $27 figure on the campaign trail as proof of his grassroots support.
