McCain should get with his democrat buddies Schumer and Durbin and write a 'bi-partisan' Bill repealing the Jones Act, and have it go through 'the regular order' that Senator McBackstab loves so much. 
Then after... oh five years... of back-and-forth with going through the appropriate Committees, having all the Hearings, the Conferences with House, then bring it up for a Vote on the Senate Floor. 
Of course Senator McTraitor will be long gone by then but hey, nothing's perfect.
