Hillary Clinton's numbers continue to fall, while support for Vermont Senator Bernie Sanders has surged significantly in Rasmussen Reports' latest look at the race for the Democratic presidential nomination.

Our latest national telephone survey finds that 50% of Likely Democratic Primary Voters still say they would vote for Clinton if their party's state primary was held today, but that’s down nine points from January and 12 points from last November. Twenty-four percent (24%) now prefer Sanders who had only four percent (4%) support nine months ago.

The remaining announced candidates - former Maryland Governor Martin O’Malley, former Rhode Island Governor Lincoln Chafee and former Virginia Senator Jim Webb - each earn just two percent (2%) of the vote from Democratic primary voters. Ten percent (10%) prefer some other candidate, while another 10% are undecided.
In the face of increasing legal questions about the safety of secrets on the private e-mail server she used as secretary of State and of the vigorous intraparty challenge from Sanders, belief that Clinton is likely to be next year's Democratic presidential nominee has dropped noticeably over the past month.

Forty-six percent (46%) of all voters - and 24% of Democrats - think Clinton should suspend her campaign for the Democratic presidential nomination until all of the legal questions about her use of the private e-mail server are resolved
