Perfect = Hillary/Obama or Obama/Hillary or Kucinich/Gravel or whatever other outcome you imagine would have made you happy even if in reality it had no real chance of ever happening or even if in reality it would have meant throwing the election to McCain.

Good = Obama/Biden

Evil = McCain/some-other-warmonger

You have to choose between Good and Evil. 

If you say that the Good and Evil choices aren't different enough to matter, then (a) you're lying for rhetorical effect but it only makes you look like a moron, and (b) you really are a moron, and (c) your choices are still only Obama or McCain, and either you're going to help get McCain elected or you're going to help get Obama elected.

Pick one.   Throw a little hissy fit first if you find it cathartic.  But then pick one of the two available options.
