Alan Abramowitz: “An analysis of the impact of Medicare for All on the 2018 House elections indicates that Democratic challengers and open seat candidates in competitive districts who endorsed a version of Medicare for All similar to that proposed by Bernie Sanders and Elizabeth Warren did significantly worse than those who did not. This negative effect, close to five points of margin after controlling for a variety of other factors, was clearly large enough to affect the outcomes of some House contests.”
“It is possible that the estimated effect of Medicare for All was a byproduct of other differences between supporters and non-supporters. For example, supporters might have taken more liberal positions on a variety of other issues as well as Medicare for All. Even if that is the case, however, these findings are not encouraging to supporters of Medicare for All. They indicate that candidates in competitive races who take positions to the left of the median voter could get punished at the polls. Democratic presidential candidates would do well to take heed of these results, particularly as the eventual nominee determines what he or she wishes to emphasize in the general election.”
