If a new election was held. would Cochran drop out?
If there is a hint of prosecutor involvement, then Cochran risks being kicked out of Congress, losing his pension and perks of congressional retirement. He will likely come up with an excuse of health to resign.
Many here have speculated wisely that the game plan has always been to have Cochran step down and have the Governor appoint a younger Barbour to the Senate seat.
Cochran did not want to run for another term. Somebody told him to do it and likely once he was reelected they would let him step down and replace him with someone the establishment approved of.
