David Koch, convention delegate

The New York Republican Party has listed David Koch, executive vice president of Wichita-based Koch Industries, among 34 at-large delegates to the Republican National Convention later this month in Tampa, according to National Journal. Koch and his brother Charles have spent heavily to deny President Obama a second term, and the Koch-backed Americans for Prosperity plans to spend $25 million more on anti-Obama ads in 11 competitive states in the coming weeks. David Koch also hosted a fundraiser for Mitt Romney last month at his estate in the Hamptons.
