Yeah, but even if the petition is successful in getting all 100,000+ signatures, how do you think the White House would actually respond? They still haven't answered yet to other successful petitions, including the Edward Snowden petition from nearly a year ago.
Typically, the white house responds, but rarely actually does anything in response to the petition. Granted, some are silly to actually allow to be act upon such as the "seceding from the union" due to Obama's re-election. The "We the People" petition site has proven itself to be more of a dog and pony show of political transparency.
I have also heard, and by all means correct me if I am wrong fellow Americans on this forum, that once you sign up an account on the "We the People" site, you will start receiving political campaign emails from the incumbent office.
