Enumerated powers, federal agencies, and Dave's bio

Challenged on a Des Moines Register piece calling his positions extreme (government should only do what the Constitution explicitly authorizes), Dave Funk defends the 17 enumerated powers of Congress and walks through the Department of Energy and Department of Education as unconstitutional overreach, then gives his bio: joined the Air Force in 1976, got sent to Omaha, grew up in Buffalo, New York, and never left Iowa.
