Hillary is a non-issue and will be forgotten soon enough. Again, I see no point is debating the "Hillary or Bust" crowd. If they prefer John McCain, there's no hope for them, us or the country.
Trying to lump all Clinton supporters under an idea that they will intentionally support McCain is just hogwash. Arguments like this just undermine what is Obama's message of unity.
In general, you and/or Obama can't speak to unity when it is only YOUR version of unity that is allowed. That is borderline fascism, and nothing short.
If you see no point in debating Clinton supporters, then why are you still posting here?
