Initially considered a long shot, Sanders won 23 primaries and caucuses and around 46% of pledged delegates to Hillary Clinton's 54%. His campaign was noted for its supporters' enthusiasm, as well as for rejecting large donations from corporations, the financial industry, and any associated Super PAC. Some of the Democratic National Committee (DNC) emails leaked to the public in June and July 2016 showed that the committee leadership had favored Clinton over him and had worked to help Clinton win the nomination.
