Rep. Jeff Duncan (R–SC)
The quote above comes from this New York Times article, in which conservative and then mainstream Republicans explain their attitudes toward the ongoing government shutdown. Interestingly, where they stand tends to correlate with how long they’ve been in office. Of the representatives quoted who supported tying a continuing resolution to defunding Obamacare, Steve King (R–IA) is the most senior, having assumed office in 2003. The next most experienced Reps in favor of shutdown were elected in 2010. It’s possible that means they haven’t been so long exposed to the corrosive effects of Washington party politics, so they’ve stayed true to their conservative principles. It’s also possible that they don’t know what they’re doing, and their confidence is a product of the Dunning-Kruger Effect.
