So some Presidents accept the limits of Executive power, and some try to take more. Who would be the ones who “accepted the limits?”

As for “institutionalized privileges for his constituencies,” can you explain how he does this any differently that all Presidents do it? If you want to learn something, read “Freedom Just around the Corner by Macauley to get some context on how such things have been done throughout our history.
What I object most to about ODS is that it relies on the outrage of generally ignorant people, or the willfully ignorant. Some are clever enough to be good Alinskians to use and exaggerate any crisis for political gain; that is par for the course. But to say such outrageous things about Obama makes the speakers sound either looney, or just plain ignorant. Obama is just a Democrat politician who happened to be elected President, but he has set loose some crazy stuff in the fever-swamp of many righty brains. The smart righties blather to persuade the gullible; the not-so-smart, because they really believe it.
Which one are you?

There are so many valid, reasonable points that can and should be made in a conservative critique of liberalism, but so often they are accompanied by a ton of cultural yahooism which communicates, if not in tongues, then with absurd swagger and name-calling, and the fact we can be anonymous here just exaggerates the whole effect. It is sort of the cartoon version of the First Amendment.
