Message tone: positive

About the message: This Sierra Club TV ad promotes Jared Polis in the four-way Democratic primary for governor. It notes his support for renewable energy. But it also touts the fact that Polis isn't taking "special interest money," while failng to mention that the multimillionaire has put $10.5 million into his campaign, or that some would consider the Sierra Club a "special interest."

About the messenger: The Sierra Club has a state-level independent spending committee to support candidates they endorse. The group may accept and spend unlimited amounts, though they aren't allowed to coordinate with candidates.

The messenger's money: The committee received $600,000 from the national Sierra Club. Because that group doesn't disclose its donors, the source would be considered "dark" money.
