Heck, I give myself some credit for managing to get the Clinton and Obama campaigns to agree on something -- that neither wanted to be associated with my remarks.
He is personally deeply loyal to the Clintons, which is perfectly appropriate - they made him. And, at the very least, Richardson could have kept his mouth shut: "Silence on his part would have spoken loudly enough."
For Carville, it's pretty straightforward: "I believe that loyalty is a cardinal virtue."
Fine. Nothing wrong with loyalty. But Carville is a political operative, not an elected official. And for someone holding an elected post, I think the loyalty should first go to the three c's: country, conscience, and constituents. Richardson's loyalty to the Clintons is superseded by his loyalty to America, his principles, and what he believes is the best for the people of his state. If James Carville can't handle that kind of complex political calculation, maybe he should keep his mouth shut.
