Trump is a carny barker—the Wizard of Oz was a displaced carny barker, by the way—whose grift happens to run counter to current elite priorities.
So he’s the target of the full measure of exaggerated spittle in defense of globalized economic and security policies that support the economic interests of the elite, and attacks exhibiting a thoroughgoing disdain for non-expert/non-elite rule. Remarkable to me, at least, because following the wisdom of elites has been a barely contained disaster for the last two decades…and apparently nobody wants to talk about that.
Actually, quite the achievement by President Obama, whose disciplined, cerebral demeanor and heroic efforts in keeping the wheels on the neoliberal sh*twagon did a lot to help claim the mantle of responsible and respectable minority for African Americans, while nudging freaked-out conservative whites out of the "value voter" political sweet spot and into the zone of "bigoted, gun-hugging bitters."
The revolutionary elite retained its affection for independence and local impunity after the British were gone, and simply transferred it to the hapless and impotent post-1776 US confederation.
During the War of 1812, Federalists organized the Hartford Convention to advance their pro-British/anti-embargo/pro-manufacturing interests and priorities against the policy of the central government. Their activities carried the faint but undeniable whiff of secession. The governor of Massachusetts even dispatched an emissary to discuss a separate peace with Great Britain. This treasonous exercise never caught on, as the war ended rather abruptly and favorably for the United States,and to the considerable discomfiture of the northerners.
