The bet here is Erickson will never sub-host for Rush again.
Keep in mind Chris Mathews sub-hosted for Rush but that was short lived.
Though Rush is in a bit of a conundrum here.
Can he acquiesce to an email and Twitter campaign to get Erickson off the air, and at the same time resist similar campaigns by the Michael J. Fox/Sandra Fluke crowd to take HIM off the air?
Rove also subbed in the past.
If enough people say they won’t listen if EE subs, Rush will notice.
He owes more loyality to his listeners than he does to Erika.
