And buried in a (Left leaning) Quinnipiac poll are some numbers that should rock Democrats back on their heals: Two weeks ago, white women were favoring Democrats on a generic congressional ballot by 13 points. One week later it was down to five points. In the latest poll, it is at one point. These are the vaunted suburban female voters that Democrats having been targeting because of their supposed discomfort with Trump. But it turns out they have sons and husbands and watching what happened to Brett Kavanaugh has not sat well.
You are quite right and the trends are all in the right direction. They ought to be worried and what we should be doing is kicking them when they are down.
