Americans for Prosperity ... is financed by the oil billionaires Charles G. and David H. Koch to advance conservative causes. In cities and counties across the country ... the Koch brothers are fueling a fight against public transit. At the heart of their effort is a network of activists who use a sophisticated data service built by the Kochs, called i360, that helps them identify and rally voters who are inclined to their worldview. It is a particularly powerful version of the technologies used by major political parties. In places like Nashville, Koch-financed activists are finding tremendous success. Early polling ... suggested that [a] $5.4 billion transit plan would easily pass. But the outcome of the May 1 ballot stunned the city: a landslide victory for the anti-transit camp. The Kochs' opposition to transit spending ... dovetails with their financial interests, which benefit from automobiles and highways. Even as Americans for Prosperity opposes public investment in transit, it supports spending tax money on highways and roads. Since 2015, Americans for Prosperity has coordinated door-to-door anti-transit canvassing campaigns for at least seven local or state-level ballots. Americans for Prosperity and other Koch-backed groups have also opposed more than two dozen other transit-related measures ... by organizing phone banks, running advertising campaigns, staging public forums, issuing reports and writing opinion pieces in local publications.
