I think you're dead wrong.
I am a liberal. Voted for Obama twice, Hillary once. Etc... I voted for them based on a myriad of things; they support a social safety net as the cornerstone of our society, want to preserve social security, pro-choice, they are pro-union....any number of issues.
That being said,
I'm for nuclear energy. We've had nuke reactors on Navy ships for 40+ years, few issues. We can duplicate that on land.
I'm for voter IDs. We have an opportunity to make the electoral process more sterile. Not taking it is dumb.
I'm for the border wall as a way to keep WMD payloads out of the country. It won't stop illegal immigration; saying it will is stupid.
I'm for closing as many foreign embassies and consulates as possible. We don't need embassies in both Budapest and Vienna for example; 3 hour car trip between the two.
I could point out a host of other conservative initiatives I am behind. Everything from re-empowering vocational education in our schools to supporting the electoral college to getting rid of federal funding for the Corp. for public broadcasting. One of my favorite was Mitt Romney's idea to have congressional action for any EPA ruling that would seriously impact the workforce or economy of an area.
I don't think I'm that unusual frankly. All of us are shades of purple. Some are far more red or blue than directly purple but with most of us, you can always go more left or further right.
I think that the two parties however often are "for" or "against" something because they (on the macro level) assume the opposite position on an issue because they can fund raise on it and get votes as a result. Here is an example. I haven't followed your posts enough to know where you stand on the spectrum so I'm not asking "you" directly but I am asking anyone who cares to comment; do you honestly believe Donald Trump who has likely never fired a gun in his life cares about your rights to have an Uzi or MP10? I imagine he does innately support the concept of self defense but I would think that if the GOP and his supporters were of the opinion that an Uzi or MP10 were "over the top", he would mirror where they are; not be the leader of the movement. So you get bad legislation based on what they think will salve their constituents; not what would be the winning solution. The Castle Doctrine in Florida is a good example. Gun nuts wanted it. Gun nuts got it. And now you flick off your safety before you say good morning to someone at Disney World.
Anyway, the Center is where the best legislation comes from. If everybody is somewhat unhappy, that is good government. Government isn't (or shouldn't be anyway) a solution to all of our problems. It's supposed to open the door for you, not give you a conveyor belt to stand on as you go through it. When something is proposed, the center isn't where it starts. It starts on the wings and becomes less toxic as you have more people consider it.
Voter ID at the state level, I'm okay with.
But we're routinely seeing people on the left and right compromising for National ID. That's a big problem. And the immigration issue is what is going to give us National ID. I've read the legislation. It's bad. It gives government an open door, limitless, to pretty much biomtrically monitor every aspect of our lives if they want. What's worse, is they keep leaving the legislation arbitrarily open ended in the name of security. In other words, they can add to it if some three letter alphabet agency wants more power.
National ID is the very antithesis for freedom and is a reflection of a government who fears the people.
Trump's comment on guns was take guns first, due process later.
I don't like the wall. It's going to hinder us more than them. All that's gonna do is keep us in. And our wealth. That's a whole different topic, though. a lot of people have their wealth confiscated by the government at the border as it is, and it takes years to get it back, if at all.
Social Security? Meh. I'd abolish it gradually. It's broke anyway, thanks to the Keynesian monetary policy we run.
Energy? Hm. Right now I like hemp. Rand Paul was just talking about legalizing its manufacturing. But...the government shouldn't be subsidizing energy. All that does is kill competition.
As far as voting? I've wrote-in Ron Paul the last three general elections. And kept busy during his '08 and '12 campmaigns in one manner or another. I'm an old school liberal.

It was refreshing to see that he still got 1 electoral vote in the 2016. That tells me there;s still a few refuseniks out there who want to kee pthe government limited for liberty.
I pretty much reject everything that comes out of Washington from both parties, because it almost always advocates for more government, more spending, more money printing, more war, and less liberty, aside from any legislation Massie, Rand, Amash, and company write. I like them.
