1) I worry the Johnson camp is only where it is and has the support it has for the same reason you see a lot of dems and repubs are voting for their candidate...so the other one doesn't win. I tend to be a 'conservative libertarian' myself...but think GJ is only getting the traction he is, just so Clinton/trump 'don't get in'. What makes GJ so much better than any other politician??? The main argument I've heard is that he's not Hillary or Donald...which I don't think is a very sound voting strategy.
Sadly, I think it's true that a lot of people are falling his way from distaste from the other two, but at least to me, there's way more to him than that.
for example, between him and his running mate - both 2-term governors, who were both at least reasonably and at times highly rated in their states, have WAAAAY more experience actually running a governmental body than either of the others.
Trump has zero at this, and Clinton has just been an appointee of a dept she was horrible at.
More importantly, both were at odds view and party-wise with the congress they led, and yet were still reasonably successful. That to me is a major issue - whoever is President next will have to know how to work w/ people who don't like them very much or share their ideology. Unlike the other candidates, Johnson has a record of being in this very spot.
I'm a believer that being a governor is probably the best training for what it's like to be president. Certainly being an authoritarian CEO isn't, nor is being a 1-term senator or Sec. of state. Sadly, I do have to admit that at least Hillary has more first-hand experience on what goes on in the office (which may, or may not be good news, but she does at least know.)
Say a third party candidate does get voted in, then what ?
Now both Dems and GOP have a leader neither want. And you think GOP pushing back on Obama was a show ? Lame Duck doesn't begin to describe it.
I actually see having a 3rd party outsider as the President a good thing, and it may seem strange but I think it's better that there isn't a matching contingency in Congress. (this is in argument to those who say, "they should grow the base first and get some Congressional and local seats").
Why? Well, first of all that means they have to be able to stand on their own, and willing to work w/ both parties, instead of relying on a contingency of friends to ram things through (a la typical party politics). It really breaks down the typical "align w/ the party" view, and comes down to what an INDIVIDUAL representative actually believes. Basically by not having a large party representation or presence in the political sphere, it forces people to consider the person as they are themselves, and not by the party label.
Maybe more importantly, it also means that some of the more crazy things that come w/ the Libertarian ticket are basically kept in check. E.g. a 3rd party president w/o a matching congressional contingency isn't going to be able to do anything to extreme b/c they will have limited support. Remember the Pres doesn't make or even start laws, they have to have a buddy in Congress do it.
