Republicans can't force their Missouri Senate candidate to drop out. But if he wants to, he has two options.1. Voluntarily, by 5 p.m. on the 11th Tuesday before the election. That deadline is tomorrow.
2. Akin can withdraw by court order, which "shall be freely given" unless the election authority opposes the request and shows good cause. That deadline is the sixth Tuesday before the election, Sept. 25th. Akin would have to pay any costs for reprinting ballots.
The Republican state committee would pick a replacement.
