Uhhhh not really. Use the Goggle Force and one will see that 'restricting immigration' is a recent innovation for Libertarians.....
While I would vote for a Libertarian/Populist over a Democrat/Traitor any day, they do need to repudiate their past support for open borders.
And as we see, when they do, they win elections. And frankly, the Paul's are more Populists rather than classic Libertarians. (Not that there is anything wrong with that)
So fellers, hitch up them sixty inch waist pants of your'in, and put the word out ..... "We have seen the Light!!"
So, you're only real objection to "Libertarians" are the ones who sit around their basement playing D&D and supporting Open Borders in theory, while never actually doing anything about it; whereas you're willing to admit that the Libertarians who actually get off their duff and get Elected, DO tend to be staunchly Pro-Border Security.
Well, you might acknowledge that, just for the sake of intellectual honesty.
