It sure seems like the point of the impeachment, anyway, is to swing the election by influencing uninformed voters. Getting impeachment through the Senate seems almost impossible, but they don't need it. All they need is to get the 24 hour news cycle saying "impeachment" every day. It won't swing existing partisans but it'll program your average tuned-out passive voter. "Oh, he's being impeached? Must be bad. Orange Man Bad."
