Exactly. Stressing commonality is very important.
I agree that it is most effective to lead with what you have in common, yes.
Ron Paul's ceiling was always limited because he was obsessed with focusing on the things separating him from the rest of the GOP while rarely stressing the areas of agreement.
I hope you are not implying that those principles that all real conservatives used to believe, be somehow buried and never mentioned. Because that will not be happening, nor should it.
You talk about the GOP like it is some kind of singular-mind monolith and it NEVER has been. There were big government Rockefeller-Republicans, who had much more in common with their leftist brethren, than the Goldwater-conservatives who also existed in the Republican Party. When the Trotskyites entered the Republican Party under the name of neoconservatives, during Reagan's run, the Rockefeller-Republicans had some new big government buddies; although they differed on a few issues. The Goldwater-conservatives were overrun by a bunch of big government Republicans from 2 camps who, after Reagan, ALL called themselves conservatives. Eventually, the "neo" was dropped and the takeover of the conservative movement as it existed, was complete.
Some of the Goldwater-conservatives left the Republican Party in disgust, others were propagandized by the likes of FOX news and some just wondered what the hell had happened.
Ron Paul DID wake up some of those real conservatives. It had been so long since they had heard anyone talk like that. I had friends who told me, wow, I remember that. Still others could not hear him and that is my hope for Rand; that he will be able to break through the wall in their minds that years of propaganda has built.
So yes, I believe in persuasion, as you suggest. Because it is usually the most effective way of winning people over. But, I also am not so naive to believe that we will win everyone over, because some have never believed in limited government and individual liberty. The good thing is, we don't need to win everyone over.
Rand Paul is doing the exact opposite and that's why he can become a credible national candidate.
Rand is leading with the issues that most Republicans like for a reason. It brings down walls in peoples' minds. But, while he is doing that, he is also slowly chinking away at the sacred cows that the neoconservatives built and will continue to do so until they no longer exist.
But, I have this to say about your use of the word, "credible". While Ron Paul will likely never become President, his two runs opened the eyes of so very many and it is those people and the remnant that Dr. Paul talked of so often, who have scared the ever-lovin' beejeezus out of the establishment insiders who are taking our country down. So, say what you will about Ron Paul, but we wouldn't be here talking today, if he had not done what he did.
