Polls show Bernie Sanders popularity among all voters is plummeting

One issue for Sanders is the erosion in the support he received in 2016. He won New Hampshire with nearly 60 percent of the vote. He lost Iowa but ended up in a near-tie with Clinton. Today, his support in both those states lags significantly from those performances. In a field of 20-plus candidates, Sanders doesn’t need nearly the level of support he got in 2016 to win or be a significant factor, but his current poll average in New Hampshire of 15 percent is not a healthy sign.

Sanders has a loyal base. The question is just how big or small that core support is. He is being squeezed from several directions.

Biden obviously is having some impact on Sanders right now, particularly with self-identified Democrats, some of whom question Sanders’s party allegiance. He also could have a bigger challenge in persuading a broad swath of Democratic primary voters that he would be the party’s strongest challenger against Trump.

Sanders is being challenged in another way by Sen. Elizabeth Warren (Mass.). In 2016, Sanders was the unquestioned leader in the offering of big, progressive ideas. Now, that’s far less the case: Others in the field have embraced some of his 2016 ideas, such as Medicare-for-all. Warren has gone further, offering specific policies on child care and student-debt relief, along with a wealth tax that she says would provide the revenue to pay for her initiatives. Sanders no longer has a premium on big ideas.
