GOPe is a legitimate honest term. There is the GOP and then there is the corrupt self-serving leadership that is part of the Uni-Party in DC that opposes the People.
The ones who attack the Tea Party and work with the Democrats to harm conservatives (Cochran debacle for example) are the Establishment. Democrats In All But Label Only aka DIABLO.
The proof that this was an illegitimate usage is that for the first half of the campaign, Donald's talking point against Cruz was that the whole GOP hated him and he couldn't get along. Now we're supposed to believe that Cruz is part of the establishment, even though the establishment hates him?
I know it's asking a lot of Trump supporters to use their brains, but think on this: every time a Cruz supporter, like me, sees a sophomoric (the "Pee" sound at the end is not unintentional) made-up term used by Trump supporters to insult Cruz and his supporters, that makes us feel anger towards you and Trump, and creates disunity, not the unity Jim Robinson claimed to be asking for.
