He has provided data-driven strategy to hundreds of campaigns, including multiple Presidential campaigns, and more than 30 members of Congress. Danny enjoys visiting new districts, hanging out in call time rooms, and matching campaigns with rising-star staff. He wants GAC's technology to help elect representatives with greater cultural, income, and occupational diversity.

Sarah Elizabeth Pole

Director of Marketing & Communications

As someone who has lived only in red and purple states, Sarah Elizabeth believes strongly in the importance of representative government. It is this that drives Sarah Elizabeth to encourage progressive candidates to run up and down the ballot. She looks forward to seeing more women and minorities win each cycle, and hopes GA will continue to help make that a reality.
