I called up my sister today to talk to her about this since she lives in Montgomery. I mentioned that maybe they could vote on it while he ran to the bathroom, to which she replied by saying they have a history of not going to the bathroom, as illustrated in this article. In Alabama, Senate Ends Bitter Rift Over Leader - The New York Times
"Mr. Siegelman called a special session of the Legislature to solve the dispute, but tension ran so high that Mr. Windom refused to leave the chamber even for a bathroom break during the round-the-clock session, lest Democrats find a way to replace him.

and the remark was picked up by headline writers, radio talk shows and national television programs, making the situation appear ridiculous."
Hopefully this thing will pass next week when they reconvene.
