Andrew Sullivan is a conservative who has written a powerful and exact analysis of Obama's speech last night. Here is a small excerpt, do yourself a favor and read the entire article because it is worth every word.

He starts with:

But it made the case for that liberalism - in the context of the decline of the American dream, and the rise of cynicism and the collapse of cultural unity. His ability to portray that liberalism as a patriotic, unifying, ennobling tradition makes him the most lethal and remarkable Democratic figure since John F Kennedy.

And it gets better.
