With Ohio (probably) losing two seats it's going to be tough keeping all 13 Republicans. Current delegation is 13 R - 5 D.
Gibbs will probably have an easier time than Bill Johnson as Gibbs holds the old Bob Nye seat and Johnson holds the Strickland/Wilson seat.
Johnson was a much better candidate, and I anticipate will be a stronger Congressman.
If the two are paired in one district (not sure if that is likely) Gibbs could win a primary, but I'd back Johnson for sure.
