Although they both end up ahead in most polls, Sanders’ margin over Trump is generally very comfortable, while Clinton’s is smaller. Clinton’s average lead over Trump is just 2.8%, while Sanders’ lead is a full 6 points
. . .
Then there’s the data about how each candidate is perceived. Put simply, Hillary Clinton is an extremely unpopular political figure. By contrast, even after enduring months of attacks from the Clinton camp and its large number of media surrogates, Sanders remains a popular figure.
. . .
