Several points to make here ...
The Democrats are playing to their base - especially women voters. Even if Kavanaugh is confirmed, with the massive and FREE MSM non-critical coverage of this accusation, they win votes as evidenced by the polling.
The polling helps drive this as they see no negative to drawing this out as long as they can. Political ads do cost money, but when they can get the LEFTist MSM to do it as ‘news’, it is free!
There will never be an admission from the LEFT that this has been political, just as they have never been sorry for any ‘dirty trick’ they have committed. From Robert Bork, Clarence Thomas to Harry Reid’s 2016 calumny against Romney for unpaid income tax to Bush’41 and the SR-71 flight to Paris, they play this as a blood sport and win because the popular culture is consistently LEFTist.
How can any woman who has a husband, brother and, especially, son, vote for a Democrat? Maybe there are just so many of them who are really man-haters without any of the above who they care about.
They seem to believe that all men are evil. It is the Dems who are actually evil.
