They're not giving Dr. Paul money for charity there bub.
If they're donating to him, they endorse him and his message, no different than Bush holding $2,300-a-plate fundraisers.
If you’d have bothered to check the context of my reply to Darkwing, you might have noticed that I was actually replying to
“...If you are active duty, using your position or rank to endorse a political candidate is forbidden.”
thereby inferring that making a monetary donation somehow constitutes an illegal endorsement. Jeez. Thanks for enlightening me, FRiend.
