It's easy to locked in to just the Presidency, especially in this cycle, but if you are truly worried about your public lands and the hunting heritage that goes along with it, as well as every other issue, you have think multi-dimension-ally. For example:
Trump wins, with the GOP maintaining majority in both houses. Rob Bishop & crew are ready to drop transfer legislation, and if it's attached to other must-pass bills like the National Defense Authorization Act or a continuing resolution to keep the Gov't open, what would Trump do? Are your public lands a negotiating tool for him, or are they truly inviolate? Same goes for Supreme Court nominatons - will he appoint judges who have a firm grasp of public land law over the last 200 years, or will he appoint Transfer supporters like Mike Lee of UT?
Trump wins - Senate goes blue - nothing happens either way. No appointments get voted on regarding SUPCO, no legislation gets passed on transfer, yet we will continue to have the repeated attacks from the House on public lands and agency funding.
Clinton Wins, Senate goes blue - Land management budgets get increased, multiple use remains in place, and land management would likely be better due to the need for the GOP to compromise to move anything for another 4-8 years. 8 years of obstruction on domestic issues under Obama have proven that their strategy is a long term party killer, so they move to the middle, and find that common ground. Clinton appoints liberal judges, who could influence the 2nd, but not very much since congress will not pass restrictive gun control, having learned the lessons of 94 and what mid-term stupidity can cause for a majority. Senate confirms appointments, setting the stage for different fights on the second, but public lands are safe.
Clinton wins, Congress stays red: Gridlock with no incentive for anyone to move anything positive forward so we get 8 more years of malarkey. Appointments to SUPCO will have to be moderate if any chance of seating them is to be had, leading to more conservative choices for SUPCO than if she had congress to do her bidding.
Trump has said repeatedly that he'd put people in cabinet positions for interior and ag that represent industry, rather than a balanced approach. He's also had surrogates talking about selling off assets to reduce national debt. One hand doesn't seem to know what the other is thinking, and with Trump, I don't think we'll ever really know what he wants to do until he does it, and then reverses himself a few times.
With Clinton, we know that she's not as friendly to the second amendment, but she does have a lot of support from the broader conservation community, is working with a number of groups who do have hunting as part of their mission, and has a track record as a senator of supporting public lands and the management thereof. Billy Jeff also had a pretty spotty record on public lands, as he was fairly fond of fracking and increased domestic production on those lands, and helped usher in the boom of the early 2000's in the west by relaxing regulations.
To me, the edge is to Clinton. I do know what we'll get, it's not going to be radically different than what we've had for the last 8 years, which for public lands was pretty good at the executive level. Trump is an unknown, and his inability to put forth a cohesive public land message is troubling.
However, the bigger issue, IMO, is congress. Congress sets the budget, passes the laws and creates our biggest problems. 535 people making some pretty poor decisions based on a system that rewards insider trading and corrupt practices. If you want to protect your public land heritage, then focus on making congress work. Moderate and thoughtful conservatives and liberals are like neutrons and protons in an atom - you have to have both in order to have a functioning Atom that isn't dead set on just eating itself alive and exploding, causing a chain reaction that makes us all glow in the dark.
