Johnson used to be Governor of New Mexico (one of my fav states). He also used to be a Republican. So he too is sorta traditional.
Most of his positions are too vaguely stated for me to comment, but on taxes he favors CONSUMPTION tax, which is frankly the better way to handle all taxes. Beyond that, I'm not at all clear what he's for or against, can't find policy specifics.
