If you look at true libertarians, they are way more conservative than the insanity that has become the Republican party.
While there are extremists in any group, most libertarians just want a common sense economic policy to greatly reduce spending. The media loves to dump on them and tell you how "crazy" they are. CNN was giving lots of air time to the libertarians until they realized Hillary was losing and suddenly started running anti-libertarian hit pieces. (maybe they should have run pieces telling people why Hillary was a good choice?)
They may be fringe candidates, but they aren't fringe ideas. It is actually a lot of simple things that a lot of people could agree on.
The Republicans are worshiping a former reality tv star who is a compulsive liar, but libertarians are crazy? The GOP talks about the deficit all the time, but just keeps spending and spending and spending.
At this point through most indies have fallen in line with the Democrats as we have to get this insanity out of the White House.
