There are any number of PACs registered with the Idaho Secretary of State. Some are active, some not so active. Most are not high dollar entities. Here's an interesting and well funded one. Winning for Idaho. (Click to enlarge)
$75,200 cash on hand. Not too bad, given that it had $0 at the start of the year. Note below that $75,000 of that came from Coeur d'Alene Racing Limited Partnership. Also note that all donations came in the last few days in December.
Who is in the partnership? 3 guys from Alabama.
I wonder what they want? It'll be interesting to see who benefits from their largess.
Update: See interesting speculation in the comments about slot machines in the N. Idaho Racetrack.
