Can Obama actually take questions that aren't planted?

If you can't have a "town hall meeting" without planting people to ask the questions don't have one at all. Have a televised address where you just read through your talking points and don't take questions. Or at a minimum get plants that aren't so connected to the democrat political machine that it only takes a matter of hours to uncover.
