It’s true the subject hasn’t come up in the campaign, but I would be surprised if Trump doesn’t have a policy. I certainly hope that the “federal” land will be turned over to the states, and ultimately to citizens.
Trump talked a bit about it back in January. Although in one article he talks about how it should stay under Federal control (the Field & Stream quotes), and in another article he talks about how the Feds should loosen their grip.
It would be nice to have a good discussion on this important issue to provide input and put together a good policy rather than just some rabble-rousers shouting at him as he is trying to give a speech.
