Folks for some reason cannot nor will not stop watching Sarah then.
This gauntlet of debates that the GOP candidates have to go through right now is like a series of minefields with the MSM given chances to snipe and cut up the field.
Meanwhile Obama is able to go around unscathed by the process.
Sarah Palin can also be unscathed by staying out of the fray for now.
