It Takes More Than Just a Good President
Besides, this entire discussion is academic. I'll be hated for saying this but I believe it to be true: Ron Paul is not likely to get the Republican nomination. My most realistic hopes for this campaign are for it to spread the message of liberty and limited government.
For sake of discussion, let's say that somehow Ron Paul pulls it off, wins the nomination, and gets elected. Unless there are substantial changes in the makeup of Congress, he will face the worst legislative gridlock in history, which makes the current standoff between Bush and the Reid/Pelosi led Congress seem like a group hug.
Besides increasing awareness, we need more Ron Pauls in Congress to help push a constitutional legislative agenda, regardless of who the President is. In some ways, if we could get more Ron Paul-like representatives into the House (where all spending bills must originate), we'd also be much better off.
If you want to see a model of this at the state level, go look at state government in Hawaii today. We reelected Republican governor Linda Lingle in a landslide, but there was no corresponding coat tails to elect like minded legislators. She's no Ron Paul for sure as Hawaii is one of the most liberal and socialist states in the nation, but even her meager fiscally conservative agenda is dead on arrival due to her vetoes being overridden and the Democrats not confirming some of her appointees.
Realistically, without a matching revolution in Congress, a President Paul could veto unconstitutional legislation week after week, but without changes in Congress, he'd be facing lots of veto overrides and a Supreme Court that interprets those laws that is split between conservative justices and those liberal justices that want to legislate from the bench.
At the very minimum, hopefully Dr. Paul's candidacy will encourage like minded people to become active in politics at the local and state levels as well so that the "Ron Paul Revolution" will stick. Best case, we need a large enough block of representatives and senators to help keep Dr. Paul's vetoes from being overridden. Ideally, the block would be large enough to keep unconstitutional legislation from being passed in the first place.
The big benefit from the Meet Ups that I see is besides supporting efforts to elect Dr. Paul, we can encourage and cultivate people who love the Constitution who have been marginalized or sitting on the bench to get back into politics for love of country and Constitution, not money.
