Up until this point, we’ve been pretty hesitant to read too much into any one of the post-debate polls — largely because for each poll that showed Sen. Bernie Sanders on the upswing, there was another poll that showed him on the downturn. But now with four more national polls and six early-state surveys (three from Iowa and three from New Hampshire) since we last checked in, we’ve got a much clearer picture of where things stand. And one thing that’s immediately obvious is that Sanders really has gained in the polls.
Sanders’s chances of winning a majority of pledged delegates has increased by 4 percentage points since Friday, up from 22 percent to 26 percent in our forecast. But notably, his gain hasn’t come at the expense of former Vice President Joe Biden. In fact, Biden’s odds are unchanged — he still has a 42 percent shot at winning a majority of pledged delegates, which was also the case on Friday. Sen Elizabeth Warren, on the other hand, slipped 5 points since Friday, and is now roughly tied with Buttigieg in our overall delegate forecast. (Buttigieg’s odds remain the same, and the chance that no candidate wins a majority of pledged delegates ticked up very slightly.)
