Arizona Congressman, Jeff Flake, has not always been the darling of the Republican party, but that’s certainly not due to his fiscal conservative bona fides. Indeed, Flake is one of those rarest of creatures: an honest politician, and this does not always put him in his own party’s good graces.

On issues from earmarks (at his website he spotlights ‘egregious earmarks of the week’) to the Cuban trade embargo which he opposes, Flake often departs from party leadership. Flake has even supported an effort to impose a carbon tax on fossil fuel producers, noting, “The first axiom of economics is if you want less of something, you tax it. Obviously, we want less carbon, so we tax it.”
