I think you've hit on it. The toppling of the elites in DC is going to take along not a few conservatives who have been the darlings of the conservative establishment for a long time.
The "little people" is a mighty giant just beginning to flex muscles.
Who are you refering to as "blueblood conservatives"?
I think it is more wondering who exactly appointed us the guardians of the world and by what authority and justification that we are going to meddle in any country that strikes our fancy. Conservatives tend to have this odd notion that the providing for the common defense means that you defend against attacks against the Republic. Pre-emptive invasion of a sovereign nation might be justified in light of an imminent threat, as was thought to be the case in Iraq. But, carried to their logical extreme, the globalist interventionalist strategy outlined in yesterday's inaugural seem like nothing more than the foreign policy equivalent of hate crimes legislation domestically. We will now execute pre-emptively against perceived possible threats rather than actual ones. And of course, the immediate response will be "well, we aren't really going to go that far....just the threat will be enough." But given the tendency for governments to expand their authority and power by whatever means necessary, it won't be long before justifications will be made for just that type of policy. In any case, comfortingly, this was almost just rhetoric. Business with China and Pakistan and other beacons of "democracy" will continue. Principle will be sacrificed to expediency. Condi as much as said so to the Senate this week. You wash our hands and we'll turn a bit of a blind eye. We may frown a bit and stamp our feet, but don't worry....our bark is worse than our bite. But we will at least have conditioned the sheep that we can interfere in any manner we deem acceptable with other sovereign nations. We're just going to replace UN-dominated world government with US-dominated world government. After all....we mean well, and you'll get to like it after awhile.
