You live in a fantasy world. Everyone has heard of him. I would guess lots do not know much about him. But your a fool if you think that everyone is voting for Trump or Hillary. I know that third party voting is going to be extensive. Not enough to win but you never know if Trump or Clinton will make it to 270.
Glenn Beck actually interviewed one of the characters who spoke on the film. A point was well made, whether or not you like ALL of Johnson's stances on the issues; he still better than Hillary or Trump at least knows the Constitution and is the only 3rd party candidate who has made it on the ballot in all 50 states. That in itself is a huge accomplishment as meeting requirements for a 3rd party is much more difficult than for the GOP or the DEM. Secondly, IF he is able to successfully get more than 5% of the electoral vote, that would be very significant and not only does it send a clear message, but sets up the party for further success next election cycle.
Secondly, Johnson is doing well in NM, McMullin is actually ahead of Clinton and Trump in Utah and is doing well in Idaho. IF enough people vote third party, there is a slight possibility it could deny Clinton and Trump the majority.
IMHO, I think it is very important for people to realize that they have a choice other than Clinton and Trump; however, I also think it is very important for people to realize what is at stake this election.
As Cruz stated; don't sit home, vote your conscience and vote down ballot.
