“…In assessing legislative shirk ing, many scholars who study legislative behavior readily admit that it is not particularly easy to determine if there is a gap between a legislator's actions and the median preference of his or her constituency (Burden, 2007;Uslaner, 1999). Moreover, researchers have found that legislators are often poor esti mators of their constituents' views on certain issues (Hedlund & Friesema, 1972;Uslaner & Weber, 1979). Thus, when assessing legislative shirking, most studies use proxies to measure the preferences of legislators' constituen cies (Kalt & Zupan, 1990;Lawrence, 2007;Lott, 1987;Poole & Romer, 1993;Rothenberg & Sanders, 2000; but see Garrett, 1999;Smith, 2001).…”
