css float issue

Normally, I would be able to fix this sort of thing but today I guess I am not in my element. I cannot seem to figure out why it is not working. I am pretty sure once you present the solution and I would feel embarrassed. I cannot seem to be able to have content pushing down the footer. If I eliminate the widget areas then it would work fine. For some reason, it is not recognizing widget area expanding in the height if content has been added.

Here is the url.
