Des Moines Register/USA Today:

The main political branch of the conservative Koch brothers’ empire is mounting a full-scale mobilization to become a transformative political power in Iowa, the state where the battle for the presidency begins.

Americans for Prosperity, which touts the virtues of low taxes and an unobtrusive government, isn’t focusing on just an election cycle or two. Its organizers openly say they’re digging in to circumvent traditional political outlets and change the landscape of politics here for a generation.
