Steve Stockman has been rumored to be a potential Constitution Party candidate for President. Now there is a Facebook page promoting his candidacy. It not clear whether the site is promoting a GOP primary run and/or a CP run.
I don’t know if Stockman is a non-interventionist on foreign policy. This has come up in the past and at the time I seem to recall that he was not a dogmatic non-interventionist, but my recollection is vague. I’ll do do some research and see what I can find out.
