Who do Democrats think should take her place?

The latest Rasmussen Reports national telephone and online survey finds that 48% of Likely Democratic Voters believe Vermont Senator Bernie Sanders, Clinton's primary rival, should be their party's nominee if health issues forced her out of the race. Twenty-two percent (22%) say Vice President Joe Biden should be the nominee, while only 14% opt for Virginia Senator Tim Kaine, the current Democratic vice presidential candidate. Nine percent (9%) of Democrats think it should be someone else. (To see survey question wording, click here.)

Among all likely voters, it's a closer contest. Thirty-six percent (36%) choose Sanders, 20% Biden and 14% Kaine. But 21% think the Democratic nominee should be someone else.

A plurality (46%) of voters believes the media is giving too much coverage to Clinton's health issues. Twenty-eight percent (28%) say there's not enough coverage, while 21% rate the level of coverage as about right.
