If the program has an end you simply can't accept new applicants OR renew your application for this variant of Deferred action.I think it speaks volumes when USCIS has not posted regulations on how an individual who was approved before under DACA may renew.I think it could only mean the Government is also hindering the program on the elections.

I am not too worried about Romney though as the days get closer to the election there appears to be ever more reason why the current President might be re-elected.
