Don’t you know that Ron Paul himself was an open-borders libertarian in 1988?

[Me] Good grief! You mean Paul is a … politician? Eiuw!

Here is the immigration platform Ron Paul is running on. I like it. He is, for example, the only candidate who has pledged to end the current, insane, interpretation of the 14th Amendment to allow birthright citizenship.
