Why is this a petition?
That is, if you're lucky - I believe we're still waiting on the promised response to this one: https://wwws.whitehouse.gov/petitions#%21/petition/actually-...
There was a petition to abandon the recent NHS reforms that reached the threshold and wasn't put forward for debate.
Incidentally, in the 24 hours after I posted that, they did in fact finally release a response to that petition. It was long after the deadline that they promise for petitions that reach the threshold, and it wasn't much more than a justification of what they already do, but at this point I doubt anybody was expecting anything more.
