If they killed Maggie off imagine what Glenn would be like. I got my money on Glenn killing the Gov off anyway.
I'm curious as to who people would choose for that task.
Merle makes sense to me. Truthfully, he and the Governor could wind up killing each other.
If it were up to me, I'd choose Rick. I think the show writers will choose Andrea, and probably at a "make a choice" moment where she either has to shoot the Governor or Rick.
Would be fun to watch the Governor arrogantly expecting her to save him only to get blasted instead

Oh, and call me sadistic but I hope the bastard dies slowly and painfully.
