The Democrats, Obama and his czars represent much more of an authoritarian threat than did Bush and company, despite Cheny's militaristic zeal, and despite the modern liberal narrative that energy and anger on the right could easily turn into authoritarian control.
Obama and the Democrats are the ones forcing us to buy insurance whether we want to or not, and it's his wife who wants to control what people eat. It's Cass Sunstein who wants to nudge as a tactic of social engineering, and when nudging doesn't work, shove. It's the healthcare law that has the potential to destroy one sixth of the economy and exercise authoritarian control over a major industry.
It's a Democrat controlled government that's seizing private companies because regulators don't like the looks of their financial health. It's the Obama financial plan to build a structure for control which now only needs to be filled in with regulations -- and it is Obama who appointed an unconfirmed Elizabeth Warren who has an ax to grind concerning Wall Street.
It's Obama putting out a hit on a private citizen without a trial. It's Obama's leadership which is sending drones like a video game to wipe out "suspected" targets in Pakistan with insufficient intelligence on the ground.
It's the left who are pushing for majority rule and violations of the Constitution, and the left who wants to drag ignorant people along to their way of thinking regardless of the people's real wishes.
If Obama is elected for four more years, and if the Democrats have any power left, we will see the real threat of authoritarianism. Of course, authoritarian control is a threat from both left and right in the political realm, but let's not be blind to which side is acting the most authoritarian at the moment.
