Maybe you are asking the wrong question? Has there ever been a President that has appointed dozens of czars, governed by executive order, and tried to divide us racially, economically, and socially? The answer to that is easy, so who knows what the bastard will attempt in the next 4 years.
Now to your response. No question that Obama has done more with executive orders and czars than anyone before him. Lame duck status could easily affect this just as it does a legislative agenda. It seems that Obama's actions are wearing on even the moderate Democrats in Congress. If you see an Obama second term, I think you'll see more aggressive opposition to him from both sides of the aisle. I have absolutely zero confidence that Romney will substantially undo the czar positions and opt instead to keep them and put his people in place who will be, if Massachusetts is any guide, only slightly less awful than Obama's appointments. The problem with Romney is that he doesn't disagree in any substantive way with any Obama position. His instincts, like Obama's, are for big-government solutions which he hopes to manage better. The problem is that after Romney puts the Republican seal of approval on these solutions, they become institutionalized, never to be abolished.
This nation is so screwed over by both candidates. If "none of the above - let's pick two others and have a do-over" were on the ballot, it would win in a landslide. Personally, I'll not be responsible for putting either of these catastrophes in office.
