The seemingly monolithic reactionary base is actually split on two issues. The first is abortion: the extreme anti-abortion activists want a very tough national ban, but most of the base views the issue with a degree of pragmatism and sees a national ban as political poison. The second is LGTBQ issues: they are catnip for social conservatives, but many reactionaries have libertarian leanings, don’t even know any trans people, and don’t see how oppressing gay and trans people will improve their lives.
What does this mean in the big picture? That any attempt to win over the base by outflanking Trump to the right was only going to peel off a handful of votes.
