That is a huge split. Women vote more than men do by a small amount…and this percentage favoring a generic Democrat on a congressional ballot is more than the percentages seen in final exits from 2016 in national voting.
We also know that there’s usually a pretty significant portion of the electorate who really like to call themselves “Independent” even though they aren’t. Here we’re seeing only a small-ish pool of independents, and 59% of women saying they prefer a Democrat, which makes that a pretty big concern.
And more importantly, having this poll not be an outlier, but being in line with another respected pollster makes this seem like the state of play a little more.
Finally, the current average on that generic ballot is about 13.5%. That’s ahead of where we were in our last three big “wave” elections, in 2002, 2006, and 2010, where about 9-10.5% was the standard preference for the party waved in during in the year before the election.
