The real problem? He's highly effective and competent (as demonstrated for instance in his management of the "Proliferation Security Initiative," one of the most effective multilateral initiatives of the Bush administration). It's that simple. It's the same reason the Rats are blocking several of the Judicial nominees, particularly Janice Rogers Brown. She's too damn smart.
I know this seems odd. A Republican Congress would focus on blocking the worst nominees of a Democrat President, but on this point as many black is white and up is down in Rat land.
"The real problem,he's highly effective and competent."Good point.Guess that's why Dems are so shook up.The idea of having someone at the UN who is actually competent is anathema to Dems and career bureaucrats.
