'Mr. Obama’s conservative opponents, on the other hand, have responded to his bold assertion of executive prerogative in two quite different ways. Some cite it as an argument for stronger checks on presidential power; others plainly believe that this unchecked power would be a fine thing if only it were exercised in pursuit of their interests.
'The first of those reactions produced the Tea Party movement, which advocated fiscal discipline, limited government and fidelity to the Constitution. Half of it joined the conservative wing of the GOP and fought elections with mixed success; the other half became an independent conservative faction out of frustration with a Republican leadership they believe has betrayed them. Many Tea Partiers now tell pollsters that they are “independents.” But the obvious leader of the entire movement is Sen. Ted Cruz.'
The Hegelian dialectic was never so useful for so little.
