If the GOP ever hopes to be competitive again, they are going to have to give more than just lip-service to the ideas of small government and quit sticking their foots so far into their mouths on social issues.
If they, the GOP, wish to revitalize and continue their party, they need to:
-Stop the atrocious foreign policy of bombing other countries and cultures simply because we disagree with them and we want to control the flow of oil. It's easy to gloss over hundreds of drone strikes, trillions of dollars, and thousands of lives spent in foreign lands as "protecting us from terror". In reality, our invasion, occupation, and destruction of third-world countries (that our leaders have deemed as a "threat") is as offensive to those people as a foreign army would be to us if they were in America. Our presence perpetuates terrorism and hatred against us rather than ending it. Our ountry needs a change in how we view our role in the world, and we should strive to spread our ideas and democracy through mutual peace and prosperity, not guns and bombs.
Furthermore, you cannot claim to be a government of small government, lower taxes, more freedom, and also support the ideas of perpetual and pre-emptive wars. We cannot maintain troops in over 130 countries around the world, fight several wars, and also balance a budget and lower taxes. Any attempt to do so or argument to the contrary is just ignoring logic.
Secondly, as we have seen over the past decade and as history has taught us, you cannot have a small government, or shrink a large one, during war time. Since the Civil War, all the way through WWI, WWII, Korean, Vietnam, Iraq, Afghanistan etc. we have seen that each time our government has grown larger and the people have grown less free during war time than in peace time. Martial laws, curfews, rations, the patriot act, the NDAA, all stand against the fundamental principles of our country and all have come out of warfare. This is a fact that conservatives often seem to overlook. If you are against bigger government, you have to also be against perpetual warfare like we've seen the past decade, because that ALWAYS opens the door for a larger, stronger, centralized government. And really, what's "conservative" about spending billions of dollars on wars?
Finally, they need to focus on restoring civil liberties and freedom to ALL citizens. Gay marriage and abortion shouldn't be decided at the federal level. The power to do so is not in the constitution and it is not the role of a government in a free society to try and legislate a desired set of morals into a country. Return the powers to the states where it belongs. Also, end the war on drugs, because not only is it not working, it's fueling the growing black market/drug cartel we are seeing and is inconsistent with the ideas of liberty and personal responsibility. The idea that the government should, and has the authority to, regulate what you as a consenting adult put into your body is ridiculous. Sure it may be a bad decision, but that's irrelevant. With the freedom to make right choices must also come the freedom to make bad ones, else you were never really free in the first place.
If the GOP were to start espousing and actually working towards the above goals, we would see them being much more effective in coming elections and they would actually start growing their base, rather than see their base shrink as they are now.
In short, they have to actually start fighting for civil liberties, smaller government, and lower taxes, rather than advocating for more warfare.
