Limbaugh says that GOP doesn't exist to win elections.

No kidding?  Coulda fooled me!  /sarc

Update:

Rush is really trying to be even handed, as I can see here. But he is really an establishment guy himself.  I think they have co opted him into serving their interest.

The trouble is that establishment co-opts things and turns it towards serving them.  You have to have a clean break from them. You don't align yourselves with them as Cruz is doing.  You don't align with them stealthily, and expect to fool people.

Cruz has lost, but he still thinks he can win by joining with the establishment.  By the way, that is giving Cruz a lot more leeway than he deserves.  I think he is establishment himself, and all of this is a great big act.

The only way for Cruz to get the nomination is for to join the establishment openly.  Then, they will love him for one of their own, because betrayal is one of their favorite tricks.

It won't matter to them if he loses, because they aren't about winning anyway.
