Trading some social conservative votes in safe states for reduce damage to him on hot button social issues in battleground states is prudent. Trump doesn’t need to worry about Florida or other solidly conservative states. He does need to worry about swing voters concerned with abortion rights elsewhere.
For all his myriad faults and shortcomings, he’s not a far right zealot on many social issues. That will displease portions of his base, but he’s savvy enough to know he has to walk a line there given how close this election may be.
