Bernie Sanders 2016 presidential campaign
As of August 15, 2015, Sanders had partially consolidated Democratic opposition to Clinton's nomination but had not significantly affected the level of support for her. A mid-September CBS poll that included Vice President Joe Biden, who is considering a presidential bid, showed Sanders leading Clinton 52 percent to Clinton's 30 percent in New Hampshire and 43 percent to Clinton's 33 percent in Iowa. In September and October 2015, latest polling show Sanders and Clinton are tied in polls.
