My feeling about Charles Koch is he should keep his wallet in his back pocket and throw his hat in the ring. Both brothers should be running for office or writing books or mentoring young people in college settings... No Republican should accept their money. These men have more to offer than money.
But with that being said, I do think that Koch is making a huge mistake by choosing to ignore the primaries and focus the efforts of Freedom Partners and Americans for Prosperity on the general election.
