Okay, site is a bit wing nut in some ways, but it makes some solid points, so read it.(standing by for the usual trolls to roll in the insults and no valid counter points)
Let's be serious, I don't think this is likely no matter who is President, Obama, Bush, Clinton, Nixon, etc. If ever a President overrules a Supreme Court ruling or tries a "coup", it will be as big an event as 1860.
