NYT:

While awaiting an internal audit headed by a top Koch Industries executive, the brothers have rejected any notion of stepping back from electoral politics. Strikingly, after years of nurturing a political network and donor base largely independent from traditional Republican circles, the Kochs are planning to substantially increase their involvement in party affairs.

They have not yet decided whether to intervene in Republican primaries, people involved in the discussions say. But the brothers want their network to play a bigger role in cultivating and promoting Republican candidates who hew to their vision of conservatism, emphasizing smaller government and deregulation more than immigration and social issues. They are also seeking closer control over groups within their network, purging or downgrading those that did not deliver last year and expanding financing for those that performed well.
