Votes don't elect our president, Delegates do, so it is a ed herring to say that we elect someone with less than 50% of the vote, when in fact they may get less than 50% and still get elected, that is the way it is supposed to work. The RINO primary however is controlled by an Oligarchy.
Campaign financing and the high cost of television advertising could be said to encourage oligarchy, but the problem is more open primaries in the early states, which give us candidates that party loyalists don't always want.
But I'm not so sure about the "Oligarchy" thing in general. The question is whether you want the party to be more representative of a particular philosophy or of opinion in the country as a whole.
Change the rules to get candidates who are more consistent ideologically but further from where most of the public is right now and somebody would still say an oligarchy controls the system, but it would be an oligarchy that you support.
But I'm done with the GOP Democrat Lite.
I was waiting for someone to say the truth. We are controlled by an Oligarchy the two parties are a joke and both are controlled by the ruling elite. In short an Oligarchy, not a Republic. In the GOP primary there were really only two candidates Ron Paul and everyone else, since everyone else was to a large degree a Bush like neocon GOPEer too, of that lot Newt was the best, Romney the worst.
