Politicians are fond of using their offices any way they can to get free publicity.
It's called boosting their name recognition with voters. That's why the name of the secretary of agriculture is always printed in large type on gas-pump inspection stickers. It's pretty harmless stuff. We should pick up our trash, use ethanol, get our unclaimed property from state vaults and stomp out forest fires. If the politician gets a little free publicity out of the deal, well, that's just one of the advantages of incumbency.
