Well it's not about consistence, it's more about unification. It does absolutely no good to be consistently wrong.
I keep talking about the "establishment GOP" and I should probably do a thread about them, but the problem Republicans have is not being too conservative or the TEA party dragging them too far right, or that conservatism is wrong, or their ideas suck... The problem is, we have a rather large contingent of people who are old school Republicans, or "establishment" republicans, and they are entrenched in power positions within the party. They gave us Bob Dole and John McCain, and now, Mitt Romney. They are currently talking Jeb Bush.... now, does any conservative out there think that Jeb Bush is the answer? I doubt it, but this is how the establishment GOP thinks, and they carry a lot of influence in the party.
The important thing to note is, the establishment wing is not the majority of republicans, it's just the strongest faction. The rest of us split our votes up among several people, while the establishment remain solid behind their establishment guy, and that's who gets the nomination by default. We have to change that dynamic, and the only way to do that is to join forces behind our own alternative candidate. First we have to admit we are a fractured party with different voices, and not some monolith the establishment wants to promote.
