As a whole, I see confusion among those who want more liberty, more adherence to the principles of the Founding Fathers. That confusion has to do with the difference between strategy and tactics, and how to use each. Strategy relates to or overall goals and ideal results. Tactics are the "boot on the ground" actions we take to bring about our strategy.
Strategy=use the means at our disposal to remove RINOs from office and replace them with actual conservatives(or what have you).
Tactics=Well, that's a bit more complicated. I believe what Micro has outlined makes sense, but it doesn't go deep enough, and misses the root cause of our current situation. I think seeing the shrinkage of government to acceptable levels within 20 years is wildly optimistic, as we have to first halt the acceleration of socialism, and then reverse the damage it has already done.
What we have to do is change a culture, a nationwide culture. It is stronger in some areas, and weaker in others, but make no mistake, America has become a nation of entitlement. Since at least the 1930s(and some would argue the late 1800s), progressives have worked their agenda to steadily undermine the principles this country was founded upon. Cultural change takes time, and effort, and frequently is less pleasant than beating ones head against a cement wall.
It begins with education. The things our children are taught in school will stay with them their entire lives, barring some life altering revelation or a determined effort by a trusted mentor. We MUST take back the schools to succeed. By that, I don't mean ban the teaching of evolution, or require daily bible study, or clubbing homosexuals in the schoolyard(all of which I have seen suggested in one place or another). I mean we must teach critical thinking, rather than rote memorization of "facts". Man-made global warming/climate change is now taught in schools as fact. The victimization of Africans and Native Americans(not sayingit didn't happen, but I take issue with the myth of the great enlightened savages), Columbus as the first white man in the new world, FDR as the great savior of our country, these things are taught as fact.
Our school system has created generations of drones who believe what they are told by authority figures without question. When they leave home and finish school, who takes the place of teachers as authority figures? All too often it is the media, and we all know how that works. We MUST teach children to think for themselves, with true objectivity, if we are to stop the ruination of our country. Entire generations have been brainwashed to the point where they can not say why they don't like something, but merely repeat what they hear on TV.
Other actions are needed, such as reclaiming state sovereignty and getting the federal fingers out of so many pies, as well as the things micro suggested. There is no quick fix available to us at this time. We have to dig in our heels and get down to work, if we wish to save this country. That requires unpleasant tasks. We may have to run for office ourselves, if we don't see anyone worth voting for locally. We may have to spend time away from family to knock on doors for those candidates we believe in.
RevDisk has some excellent suggestions there, as well.
