Your pick. Ya I realize if you go down the list of unrealistic candidates, you can include more. Gary Johnson comes to mind. We're talking about getting 50% of the nation's popular votes here, 100+million people adjusted by participation rate, not just to improve a certain party's poll numbers from 7% to 11% and blow your own trumpet calling it a success. If you're a hardcore Libertarian, you only need a fraction of that 100+million potential infusion of new blood and you instantly expand your future potential. If that's what you care about, of course. I often find many Libertarians not having a care for much of anything, it's like things just automatically get better with everyone sitting on the Libertarian couch.
