I think the areas of common ground are on more than economic issues. I think we also have common ground on regulatory issues, entitlements, 2nd amendment rights, many 10th amendment issues, abortion, morality, health care, right to work issues, energy & environmental issues and a few others. Foreign policy and some individual liberty issues (Patriot Act, indefinite detention, etc) are the ones where we part company. So when I am conversing with someone who would have views like Beck, I can name 10-15 issues where we see eye to eye before we even touch on the differences.
One thing I will disagree with you on in your post is when you referred to Beck as a neocon. He is not a textbook neocon since for one, he is with us on those issues I listed above, where a neocon is going to hold a much more moderate position on many of them. Remember, neocons are essentially pre-Great Society Democrats, so they do not hold the same positions we do on a lot of those domestic issues. Neocons support the welfare state, maybe not the one we currently have today, but they aren't universally opposed to it like we are. Beck shares that disdain for the welfare state like many old school Republicans like myself do. Additionally, from what I heard from Beck (and granted it is bits an pieces here and there throughout the years), it seems to me his interventionism is driven by security issues and not a desire to see the US as the policeman of the world. The goal of the neocons is that one world order that we hear so much about. I don't see that desire from Beck. I think his concern is that we have radical Islamists over in the Middle East that want to kill us and our allies, and that we need to prevent that from happening by taking them on over there. I disagree that we need to be involved in their affairs, as I think that is part of the problem, as I am a very old school non-interventionist (hearkening back to the Taft era). So I think it is unfair that we label Beck a neocon, as from what I heard from him, he does not share that global order goal of the neocons. I am pretty sure I have heard Beck be critical of the UN. Again that is something that we wouldn't hear from a textbook neocon like Bill Kristol, Donald Rumsfeld, or Dick Cheney.
