For one thing, they know that they're not fooling anybody, so they aren't even trying to expand their voter base. They seem to be doubling down on their rich WASP supremacy base and hoping that they can smear, lie, and cheat their way to a second term (basically going for the EC even though Trump probably wishes he would win the PV but the EC is all that he needs to stay in office and ahead of the law). For another thing, whatever "enthusiasm" or boost he might get from dumping Pence and adding somebody like Haley would probably be superseded by the anger and potential (likely) loss from the right-wing Evangelical crowd. Pence is staying right where he is and, hopefully, going down with the ship.
