The 5 issues I added to your 4, constitute the basic issues for most conservatives these days. Those issues form the starting point for advancing conservatism in the political arena. Along with defending the Constitution, of course. While governance and politics is all compromise and negotiation, once to get into office. Its to what degree you're willing to compromise and negotiate that counts the most. Upfront, there is no surrendering on the basic principles of conservatism and once in office, there shouldn't be capitulation to the loyal opposition on EVERYissue. Stealing issues from the Democrats, or efforts to out-Democrat the Democrats, is a silly effort in futility. Serves no good purpose, except to undermine the traditional American values of mainstream conservatism.
Like I said, I could increase the list to 15 key points. But the farther you get from the big 4, the more debate within conservative circles arises. For example, immigration is one that no conservative concensus has arisen for a solution - other than stopping the flow as the first step. I want to see all illegals have to return home and apply for green cards (temp workers) or else be deported permanently. And the end of anchor baby BS. But the editorial boards of mainstream conservative publications such as the WSJ, NR, and Weekly Standard have all seemed to align with a version of Bush’s plan.
