You might be surprised. They can do it quietly without a big fuss. They are going to want to prune her benefits or cut her off all together just in case someone does find out who she is, or if she decides to go public, on talk shows and such. They will take care of her, slowly and quietly. She broke the rules.
With the level of surveillance all levels of government is doing on each and every citizen every day, I have no doubt that they already know who she is. Once you get flagged in the system for anything, like voting Republican or being in the Tea Party or whatever political behavior the bureaucrat rulers consider to be unacceptable, the party is over.
Whether or not she loses her benefits, she did not do herself any favors by bringing national attention to this. She should have kept her mouth shut.
