If you go to his website under the issues section he actually explains in detail what the issue is, why it's an issue, and what process he will go through to tackle the issue. Now whether he actually makes good on his word is a different story.

If you go to Obama's website and read his issue statements, he just says he'll resolve the issues but there is no meat to the how. It's all just talk from what I see.

Personally I'd still might choose Obama over McCain. This may be a case where the devil that you don't know is a better situation than the devil that you do.
