BOISE — New finance reports show what donations came in and what money was spent between May 26 and September 30 for Idaho campaigns.

A ballot initiative seeking to legalize historical horse racing devices in Idaho that opponents contend are the equivalent of illegal slot machines is drawing the most money leading up to November's general election.

Campaign finance reports filed Wednesday with the Secretary of State's office show the Committee to Save Idaho Horse Racing, in support of Proposition 1 raised about $2 million since the May primary.

All of the contributions to the campaign came from Treasure Valley Racing LLC, the operators of Les Bois Park in Boise.
