Offer Akin $’x’ to cover his campaign “debts” and to pay his staff to get out ASAP. Make the offer a one time, take it or leave proposition with the understanding that if he doesn't take it, him, his wife, kids, parents, siblings, mailman, owner of the gas station where he fills up, etc., will learn what the terms PAIN and SUFFERING truly mean and it will all be DUE TO HIM.
And before any of the Lawrence Welk crowd attempts to retort with some half-baked bilge, I will pre-answer that:
FY, this is a war and you either fight to win or lose; there are no “moral victories”.
I imagine some of what you propose has already transpired - in “gentlemens’ terms, of course.
Even if Akin wins, his actions during this period will not be forgotten. He can’t expect any plum assignments and he will be primaried out in 2018.
