Dem's and the gang of 7 traitors have so poisoned the process that no one wants to go through it. It's sad but it should also be used as a hammer over the head of the gang of 7.
The process was already poisoned. Probably lots of people didn't want to go through it before McCain and his Merry Moderates made failure of a credentialed conservative pretty much inevitable. To go through that process has been ugly for a while; to go through it for nothing in the end isn't more appealing.
