I’m sure this comes as a shock to you.

SIOUX CITY, Iowa — Democratic presidential frontrunner Hillary Clinton’s campaign admitted Friday that it planted a global warming question in Newton, Iowa, Tuesday during a town hall meeting to discuss clean energy.

Clinton campaign spokesman Mo Elliethee admitted that the campaign had planted the question and said it would not happen again.

“On this occasion a member of our staff did discuss a possible question about Senator Clinton’s energy plan at a forum,” Elliethee said.

“However, Senator Clinton did not know which questioners she was calling on during the event. This is not standard policy and will not be repeated again.”

In a state where the caucus is held sacred and the impromptu and candid style of the town hall meeting is held dear, Clinton’s planted question may come as a great offense to Iowans.

Here’s the exchange they’re referring to:

Question: “As a young person, I’m worried about the long-term effects of global warming How does your plan combat climate change?

Clinton: “Well, you should be worried. You know, I find as I travel around Iowa that it’s usually young people that ask me about global warming.”

The Edwards campaign goes on the offensive:

“In light of a weak debate performance, not to mention a persistent inability to answer the tough questions, it appears the Clinton campaign has adopted a new strategy of planting questions,” John Edwards’ Communications Director Chris Kofinis said.

“It’s what the Clinton campaign calls the politics of planting.”

I’m not really sure his campaign should be talking, though.
