Ideally, Obama, if reelected, would meet a moral epiphany, confess his crimes, resign in shame, and return to live out his life in ignominy in Chicago serving up soup at a homeless shelter in a futile attempt to atone for his many transgressions. The problem there is that would leave us with that buffoon Biden in the presidency, and so the ideal would not be a good outcome here. Short of that, Obama's having to deal with a congress both houses of which were controlled by veto-proof majorities of the other party would be poetic justice.
If Romney is elected, I would want him to cut spending dramatically, stop waging continuous war in foreign lands that by mere coincidence have substantial supplies of strategic natural resources, start cutting regulation and taxation, and in a thousand other ways put the federal monster on a crash diet. Were he to do that, he would be unlikely to be reelected to a second term, or even to live long enough to run for it, so once again the ideal is not what we will see.
The reason I think along those lines is that America cannot survive a monolithic, totalitarian national state, which is what Washington is building. I would like to see that process halted and reversed, and so I would dream that the next president would do what he should to further than end.
