National GOP leaders have been scrambling to prove that last year’s Republican extremism was a mere aberration – that moderates and sane conservatives need no longer flee the Republican Party in terror at what it has become.  But what’s been described as the Republican Party’s “Virginia Problem” continues to worsen, as the commonwealth’s GOP agenda continues to push election-rigging, attacks on birth control, and now an anti-United Nations conspiracy theory back into the national spotlight. In the latest example, a Republican-dominated committee in Virginia’s House of Delegates has approved a joint resolution embracing the Tea Party-inspired conspiracy theory that a secret U.N. plot seeks to “covertly” enact a “radical plan” to “erode American sovereignty” through (horrors!) “sustainable development policies such as Smart Growth.”
