I seriously think this whole Kavannaugh thing is hurting the Democrats more than it is the Republicans and with it being so close to election it could put a stop to the blue wave that people were predicting.
My suspicion is that while it might generically help the Democrats (since the public at large is more opposed to Kavanaugh than not), it's not helping them in the places where they need to win, like House districts that lean slightly Republican or, for the Senate, states like North Dakota where there is (so Nate Silver claims, anyway, without providing a link) a majority in favour of confirming Kavanaugh.
Plus, especially with the Senate, those national polls are going to poll a lot of people from places like California (where a Democratic candidate is absolutely guaranteed to win) and New York (where Gillibrand is almost certain to win), and far fewer people from places like Montana, North Dakota, or West Virginia, which are seats the Democrats really need to hold and where a pro-Kavanaugh tilt won't much impact the national result.
EDIT: Meanwhile, in a recent campaign ad, a Democratic candidate for the House literally gave out his cell phone number. (I won't say who because of forum anti-doxxing rules.)

It's not the Russians, folks.
