The headings are in the Redactor field so that there is no in-page nav box. This campaign landing page also has the "Exclude Header and Footer" switch turned on so that there is no navigation at the top of the page, and the nav at the bottom is reduced to the bare minimum.
The idea is to have a clear call to action without too many choices for navigating away from the landing page and capturing user information in the form.
