GOP presidential candidates assembled last weekend at a fundraising summit hosted by the conservative mega-donors Charles and David Koch. The brothers and a confederation of like-minded donors watched as the candidates groveled for the money and support of the powerful Koch network. The candidates took two separate approaches to proving their worth and loyalty to the Koch’s brand of small government conservatism. Some, including Carly Fiorina, sought to increase their bona-fides by attacking Hillary Clinton, continuing to question her use of an email server during her time as Secretary of State. Others courted campaign dollars by heaping praise on the Kochs and their donors for their patriotism and support of Republican efforts to retake a congressional majority. The brothers tested the candidates on a variety of issues, most memorably their grilling of Scott Walker, who scrambled to defend his honor when asked how he could support using taxpayer money for an NBA stadium co-owned by a Clinton supporter. Walker argued that the team in question provides over $6.5 million each season to Wisconsin tax revenue, turning what could have been a major gaffe into a minor hiccup. Notably absent from the summit was Donald Trump, who is using his own personal wealth to finance his campaign. He denounced the attendees as “puppets,” stating “I wish good luck to all of the Republican candidates that traveled to California to beg for money etc. from the Koch Brothers.” While the Koch Network has denied that it will officially endorse any of the candidates, the financial backing of the Kochs is an indication of implicit support that would invite other mega-donors to follow suit. In a race where money means everything, kneeling before the kings of cash is part of the process.
