allow people to vote on whitehouse.gov petitions with simple email verification. Do NOT require creating an account.

In case your IT folks are too dimwitted to know it, having to create an account drives people away.

Also the current system it provides no more authentication risk than a simple email verification, is no more risky, is no more manipulable. Well, a little more, those that stuff such things for a living, it would take them fifteen more minutes to punch through your current system than to fake out email verify.

It your infosec people have not told your this, they need re-education.

So, for people who simply want to sign a petition, switch to a simple email verification.
