Yeah, I dunno, how much of this delegate sapping real and how much of it is hyped and bogus?
I always get skeptical of delegate shenanigans...too many layers of selection to go through and people tend to vote for those they know and people either know you are a rock-ribbed conservative, or not, or a Paul supporter and that representation bubbles up and can get more diluted the higher you go because the long-time PTB's in party politics tend to dominate the upper levels (mostly Ruling Class types, unfortunately)...so...
...Unless the Libertarians have mounted a mutli-decade effort to infiltrate ever level (especially the senior levels) of local and state GOP parties by posing as rank-and-file Repub's...the chances of an open convention are dim at best.
The most common form of delegate flipping occurs at the convention when the delegates for the perceived primary winner lobby the rest to throw in at some point to make the final nomination as close to unanimous as possible (aka "herd mentality").
Don't get me wrong, a brokered convention wouldn't upset me, I'm just not certain Paul is the replacement candidate I could swallow. But seeing as I would be swallowing some crap one way or another I cannot say for I would not support Paul if by some miracle he ended up the choice.
Getting Obama out is paramount...even if the alternative offers up a new set of worries...
Pretty pathetic, huh?
Welcome to the America we live in now...
