A central tenet in the electoral systems subfield is that parties, when in power and motivated by partisan interest, seek desired outcomes via the strategic adoption of electoral rules. Such a focus, however, omits a key point: electoral rules also distribute power among geographic units. If, within a party, the partisan and geographic interests of some members conflict, then the canonical relationship between partisanship and rule choice may be conditional. The U.S. electoral college provides an opportunity to test for such intra-party variation, because it advantages some states over others and thus makes salient geographic allegiances. Using an original dataset on one reform proposal—the National Popular Vote Interstate Compact (NPVIC)—I find evidence of competing loyalties. Although NPVIC advances furthest when Democrats control state lawmaking, a state's status as a swing—but not as an overrepresented—state weakens the relationship to the point where even Democrats are unlikely to aid NPVIC.
