The popularity of Sanders among all voters, however, seems to be dropping significantly in recent months.
According to our new CNN poll, Sanders is 46% cheaper than an unfavorable rating of 45% among registered voters. This is just the last survey, in which Sanders is essentially even in its net-favourability rating (favorable-unfavorable). A poll from Quinnipiac University at the end of December gave the Vermont Senator a net recoverability of only +2 points. On average across all recent polls, Sanders' net score is around -1 points.
Compare that to the place Sanders was at the end of his 2016 presidential run. Sanders had a 59% favorable rating and 36% an unfavorable rating among all voters in a CNN poll conducted in June 201
Sanders maintained much of its popularity last year. A CNN poll conducted in early December 2018 gave him a net gain rating of +13 among all voters. A Gallup survey in September 2018 had a net fitness rating of +15 for all adults.
So, what has changed? I would argue that Sanders has benefited from not being in a competitive campaign. (Former Vice President Joe Biden, who has found the most support in general election polls in Democratic elections, can benefit from a similar effect.) If you do not think of a realistic threat to a party's nomination, opponents tend to dismiss it. The last time Sanders was considered a minor threat to winning the Democratic nomination was in March 2016. His net eligibility among all voters was +3 points in a CNN survey.
at about the same level as the other individuals who own Candidacy for the Democratic nomination. However, most of these other candidates are relatively unknown. At least Sanders is not as selective at this point as the average Democrat. It's just that he can not claim that he is more eligible for national electoral procedures.
Sanders, however, must convince the Democratic voters that he is eligible. In our poll, only 30% of Democratic voters believe that the party has a better chance of winning the presidency with him than anyone else as a candidate. The vast majority (59%) think they can do better with someone else.
That may change when Biden enters the race. The big unknown is whether Biden, whose ratings are currently sky high, will also fall to earth if he explains. It's probably not a bad bet in the face of the past and what happened to Sanders. Then it will be much harder for the Democrats to find out who is the most eligible.
