In presidential politics: to pick a vice presidential candidate who hurts your campaign more than helps it and then then to subsequently sink your campaign completely by making an ill-advised or ridiculous statement in September before the election.

Named for John McCain and Mitt Romney who both achieved the feat.
John McCain vice presidential pick: Sarah Palin. September announcement to suspend his campaign to go back to Washington to work on the financial crisis.

Mitt Romney vice presidential pick: Paul Ryan. September criticism of U.S. embassy while it was then currently under attack and mistakenly accusing the current administration of pandering to terrorists.

Our vice presidential candidate is dragging us down. Let's carefully stay on message this September so we don't commit a Romcainey.
