Maybe we would see the Gary Johnson. Liberal or Left-Libertarians merge with the Ron Paul classical Libertarians and either takeover today's GOP and run the Neoconservatives out of the party. Or at least out of leadership and run that party, even merge with what's ever left of the classical conservative movement. The Goldwater/Reagan coalition in the Republican party and make the GOP a real Conservative Republican party. Which is what they aren't right now. There are millions of Americans who love both economic and personal freedom, but who aren't anti-government. They just don't want government running their lives for them and just do the basics. Including a safety net for people who truly need it, as well as law enforcement, national security and foreign policy. But these voters don't have two major parties right now who speak for them.
The other option for Gary Johnson and Ron Paul, would be to combine their factions and both go over to the Libertarian party to build that party up for the long-term that would allow that party to be a strong enough third-party. And win some elections, some seats in some state legislatures, a governorship here or there, local council seats. And even win a few seats in Congress, and some House seats here, perhaps some Senate seats over here. But that would have to be a long-term strategy. Short-term they would be better off taking over and occupying the GOP. If Gary Johnson was simply polled like President Obama and Governor Romney were during this election, he might have been at 15-20 percent. Because again he speaks for millions of Americans who aren't looking to eliminate government. But get it back to doing only what we need it to do.
