The only Catholics who will vote for Kaine are Hispanics, abortionists, and bishops.
A lot of “Catholics” who have strayed far from the path will support Hillary; “Catholics” on their third marriage outside of the Church, for example. I assume most Catholics that bother attending Mass won’t vote for Hillary (and I believe stats bear that out); I also assume there are far more Catholics that couldn’t be bothered (and the local parish closings seem to bear that out).
