The Koch brothers invest millions in Iowa properties and donate $130,000 to Iowa politicians...why?

DesMoinesRegister.com:
"Land records on file in 20 Iowa counties reveal that Koch Industries or its subsidiaries now own 18 commercial and industrial facilities valued at nearly $90 million, including four ethanol plants purchased earlier this year.

As the Kochs' business holdings here have grown, so, too, has their interest in Iowa politics. KochPac, the company's political action committee, has contributed more than $130,000 to candidates for the Legislature and statewide office since 2003, records show."
