I don’t believe the Democrats want destruction of the U.S. What they want is politics and a world that does not yet exist, except on there little Hill in Washington. The result of both parties acting like there is no world beside Washington (including our own citizens) has created tremendous blowback, but the machine on the Hill refuses to acknowledge any of it.
I disagree with you, I believe they do. Most Daily Kos - Geo. Soros leftist, Obama supporters want want to topple old institutions in the pattern of Mao's cultural revolution.
They want a Democrat Socialist hegemony with no political opposition and the elimination of the Electoral college, think John Lennon's "Imagine!"
They want all Global Warming deniers dead or impoverished and silenced by oppressive tax penalties.
They want to nationalize Business and Industry in order to make, in their minds, "every one equal" and assure that no CEO or banker will earn more that the laziest among them.
Most would even like to change our Nation's name to more completely sever all ties to a nation founded by a bunch of non diverse old men.
In short they want our nation's destruction.
