Better question:
Who does the GOP speak for?
I see you already gave a partial answer, MichaelA.

The republican party is an establishment dinosaur, as is the democratic party. They are both marketing businesses out for power and money. Thats all. There is no interest in carrying on a decent election at all. Its boring really.

You bring up some points, I call the major parties, The Big Government Party, it has 2 wings, right and left. They all do the same things, grow government and spend money, just on different things. I left the GOP during Bush1 and whole no new taxes thing. I saw where it was going and became an independent. Most of the time I hold my nose and vote R only because nothing can take the stench off a D and there usually are no others available. RINO's are just doing what that Establishment wants them to do, Buchanan is a big one, so is Graham and so many others. I do like individual politicians but they are usually sidelined and ridiculed by the political elites, so I sit and suffer only to determine that they really don't care about us, they only care about money and maintaining power (staying elected).

Who speaks for the GOP?
A Charlie McCarthy surrogate.
