Hillary Clinton announced her intention to seek the Democratic Party's nomination for president of the United States in 2016 on April 12, 2015. On that date, she launched her official campaign website, released a video explaining her desire to run for president, and tweeted her intention to do so.
In an ABC/Washington Post poll that surveyed voters between Sept. 7, 2015 and Sept. 10, 2015, Clinton received the support of 42 percent of the Democratic primary electorate. Clinton was 18 points higher than her nearest competitor, Senator Bernie Sanders, who received 24 percent, and 21 points higher than Vice President Joe Biden, who received 21 percent. Clinton's 18-point lead over Sanders represents a much smaller lead than she had in the months immediately following her announcement. In an ABC/Washington Post poll that covered the period from May 29, 2015, to June 1, 2015, Clinton received the support of 69 percent of those polled, compared to 2 percent for Sanders and 12 percent for Biden.
