The Left has historically and wrongly used the charge of racism as a potent political weapon to smear conservatives — and they’re at it again now with Rand Paul. But while Paul may be many things — a principled libertarian, a neo-isolationist, soft on defense, etc. — he’s no racist. And conservatives — at the FrumForum and elsewhere — should know better than to shamefully acquiesce in the Left’s latest attempt at character assassination.
