I'm a bit disappointed at the liberal style aggression that goes on in these forums. When civilized people have a discussion, they talk about the core points of the topic and work together to figure out the truth. The only goal of a topic should be to discover the truth, and when that happens, everybody wins. When liberals have a discussion, they use cult style aggression, put others down with personal attacks to make themselves feel better, and value quick wit & having the last word above all else. It's not a good idea to trash talk people just because you're anonymous over the internet; that's not healthy for our culture as a nation, and only feeds the liberal culture of quick wit elitism. My rule is always that I don't say things to people over the internet that I wouldn't say in a face-to-face discussion.
I already demonstrated my main points, so I'll deviate from the meat of the topic just a bit by adding some very relevant other details that support the backbone of my opinion. I've noticed for a long time that pure Libertarians never compromise or take what they can get. Before the campaigning got rolling, I even saw many around the internet, including a popular Libertarian youtuber, that said they support Ron Paul but not Rand Paul... Now the caucus dilemma we're in at the moment is quite different. I think the reason why most pure Libertarians would not support Cruz over the worse Trump and Rubio stems from what got us out of the Establishment in the first place. Most of us probably grew up in a Democrat or Republican Establishment culture. We got sucked into the two party system and found ourselves rooting for one establishment or the other. Many of us at some point became less enthusiastic about the establishment, while still rooting for an establishment nominee in the general because they are better than the other party's candidate. Then, we realized the truth about what's going on in the country and joined the liberty movement. We thought back to why we didn't join it sooner, and said "holy cow, my rooting for the lesser of two evils made me feel satisfied, like I was already doing enough, which stopped me from desiring more and discovering the liberty movement!". Then, your mind associates all compromise voting with being brainwashed by the Establishment. This is actually a well founded fear in my opinion, because willingness to fight against seduction of the mind is a very necessary trait for Americans going into the future. But there's a huge difference between a 50 year old talk radio junkie who doesn't get the point of the liberty movement voting for Ted Cruz in the primary because he planned to from the start, and a liberty voter voting for Cruz in the primary only because Paul is out. The reason why it's bad to be satisfied with a non-liberty candidate is because it makes people think they've done enough, and so they do not pursue discovery of the liberty movement. But we have already discovered the liberty movement, so that is irrelevant to us. There is also a big difference between voting in the primary for a compromise candidate and voting for a Democrat or Republican in the general election. If you vote for a Republican in the general election, you're helping the party win. If you vote for someone in a nomination primary however, it's probably not helping the party win the general because there's going to be a Republican nominee anyways. There's nothing wrong with trying to get Cruz as the Republican nominee as a compromise candidate, but then voting for Gary Johnson in the general.
Most Libertarians seem to think that the path to liberty is to go straight from Mitt Romney to Rand Paul, as if this is actually possible. It's not impossible, but it's highly unlikely to happen without an intermediate step. If the intermediate step will be inevitably necessary, why not take part in it yourself? Then there's people who think we need a third party candidate to win. By the time a third party candidate actually is able to win the general election, many liberty and conservative values in this country will likely be destroyed forever. If we took the shorter term approach by breaking up the Republican party, the Democrats would win every election and the U.S. would fall to Socialism. Therefore, the only way to have liberty be victorious before time runs out is to transform the Republican Party. If Rubio gets the nomination, we'll be right back where we were four years ago with Romney. If Cruz gets the nomination however, it will be a step in the right direction. More Republican voters will start taking the idea seriously that it's bad to get stuck in a ground war, because there's no better advertisement of ideas than someone actually winning the nomination (or becoming President). Then I'd argue that it'd benefit us the most to vote for Cruz in the general election too, for the sake of stopping a permanent fall to Socialism. But I do completely understand, if despite there being a lot of logic in voting for Cruz, if it's just too depressing for some to compromise. The emotional dread some get from having to settle on a candidate is a lot for me to expect Libertarians to put up with.
