Message tone: positive
About the message: This mailer from the Sierra Club supports Amy Beatie in Denver's three-way House District 4 primary contest. It says Beatie will "protect parks, clean are and water, and overall quality of life."
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.
