What Tom Vilsack doesn't know about any subject is considerable. This particular Secretary of Agriculture would have trouble telling you the difference between a pig and a chicken unless some toady gave him a prompt. He moved to Iowa and became a politician-cum-teachers union toady in the southern tier of the state; he's not a farmer, not a grain elevator owner, not even a certified forklift operator.
He is, in short, a credentialed Democrat who will say and do whatever he is told, and if one of his bosses would tell him tomorrow morning that climate isn't happening, Tom would contradict himself fast enough for the sonic boom to shatter every window in the Beltway.
