IMHO, Regardless, Someone like Ron Paul, doesn't connect with the majority of soldiers that have been there and done that. Despite good intentions, and his record as an Air Force Flight Surgeon (63-68), there is a separation of the True Patriotism and sacrifice, civilians and 99.99% of any politician will ever understand.
However, perhaps that is why Paul is so popular with younger voters.(Reference to the OP at the Univ. Of Iowa). Moreover, Paul correlates with young soldiers eager to do their duty and get back home to their families and be left alone from undue Gov't interference, (of which, is a good thing).
Paul was/is a "Libertarian" candidate,... in 1988, and other runs, but somehow always falls back to an "R" candidate, after realizing that is the only chance of re-election.
After many Congressional defeats and victories, the term limits he is in favor of, would have left him out of office decades ago.
