I have been unable to verify that there is a pledge. I signed up at OFA and no pledge was offered, even as a box to check.
In the “profile” section, it does have a fill-in for “why I support Barack” but no pledge.
If anyone finds it, please post it.
Maybe something was changed?
Check this out, they have screenshots of the pledge: http://sweetness-light.com/archive/obamas-very-creepy-pledge-project
