That sounds a lot like "prove to me that you don't beat your wife." Rand Paul has never said or done anything remotely anti-Semitic, unless you're one of those people who assumes that cutting foreign aid (to all countries, not just Israel) is automatically "anti-Semitic."
This is only the opening salvo of a battle to re-take the Senate from the Progressive/Liberals. Rand Paul is a needed figure to focus the rage of the nation over the Vichy Republicans and the old guard. Even Democrats are growing restless and chaffing at the bite. I believe I can hear the fife and drums of the Tea Party warming up! Sarah Palin, got that new flag ready for us? You aint seen nothin’ yet!
