If the hearing drove moderates away, then they have serious head problems. Just remember moderates, that may well be you on the stand of inquisition next.
I can name a dozen moderates who either registered or made sure their registration to vote was up to date so they could vote Donnelly out here in Indiana because of his Kavanaugh vote. Some had never and some had not voted in decades. (Factory workers, truck drivers. Men and women) Some are just now getting jobs after years of low employment.
I’m sure rural Indiana is similar to other areas of country ! These people are not on any polling lists.
