Ernst was then a little-known Iowa state senator and lieutenant colonel in the National Guard who was considering a long-shot campaign for the GOP nomination for U.S. Senate. Polls showed more than 90 percent of her states voters had no opinion of her. At least a half-dozen other Republicans ― some with better funding and connections and stronger establishment support ― also were positioning themselves to run against the presumptive Democratic nominee, Rep. Bruce Braley.
But Ernst was being watched closely by allies of the billionaire brothers Charles and David Koch, who saw in her an advocate for their brand of free-market, libertarian-infused conservatism. Operatives affiliated with the Kochs political network invited Ernst to the networks August 2013 gathering of wealthy conservative donors at a posh resort in Albuquerques Santa Ana Pueblo.
Ernst later told POLITICO she had no idea "how my name came through those channels." But her appearance at the event impressed donors and was followed by an infusion of support that helped Ernst win the GOP nomination and, eventually, a Senate seat. It also represented a new phase in the rapid expansion of the Koch-backed political network ― its willingness to become involved in primary fights among GOP candidates potentially putting it on a collision course with the official Republican Party.
