As you can tell, I do not hold rigidly to Republican=Conservative, nor Democrat=Liberal. I actually see 4 different movements here. Combine these 4 with the others out there (Independent, Libertarian, Neo-Conservative being just 3...there are more), we have several actually. The Republican and Democrat have more voice and presence only because the monies pumped into them and pumped out of them. Money talks in this country....it is often the politicial grease of our political language. That is why corporations lobby and is why most people in Government tend to be wealthy coming into it and leave wealthier coming out of it. However, being ever so mindful, we are a nation of people...a nation of Americans, great and small. In the long and short of it, a nation is often remembered and judged by NOT how often it can flex its political/military arm, but by how it takes care of its own...the common citizen.
My take on the Republican party as it stands and why it seems to be having an identity crisis is because it has pivoted itself between two movements...Conservative and Neo-Conservative...one being the original platform, the other being a once fringe movement which since had gained momentum and presence under Bush et al. As a result, a schism has occurred. So, in a way, the Republican party is fighting a war on two fronts...internal and external. And with any schism, there is chaos...and those who wish to exploit it. And since there is no firm leadership in this party any more, the schism continues.
