So much for the mother's milk of American politics. In Baltimore, it's orange juice.

Del. Keiffer Mitchell endorsed Mayor Stephanie Rawlings-Blake's re-election campaign in a video released Monday -- one day she drew crowds to his OJ stand at the farmers' market.

Coincidence? Mitchell copped to the quid pro quo when I spoke with him just now.

He said Mayor SRB came by his stand Sunday. She wasn't buying, but her photographer took a glass of juice. Soon a crowd gathered to see the mayor, and suddenly Mitchell was squeezing up a storm.

"They were standing there, 'Hey, I might as well stand in line and get some juice,'" Mitchell said. "Who says there’s no tit for tat for political endorsements?"
