Gridlock in the Government of the United States: Influence of Divided Government and Veto Players

  • Manabu Saeki
Abstract

David Mayhew’s Divided We Govern significantly challenged the conventional wisdom of the adversarial effect of divided government on government effectiveness in the United States. While the post-Mayhewian literature has been centred on legislative productivity as a measure of gridlock, gridlock is here defined as an ‘inability to change policy’. In this study, the preferences of the legislators, such as the filibuster, override and House median veto players are plotted in Euclidean space. The analysis focuses on the influence of the area of the winset, which is an intersection overlapped by the veto players’ indifference curves. There is a substantial impact of the area of the winset on the change in policy output point, which is measured by the ADA scores and by Poole’s Mean Winning Coordinate. Yet divided government has marginal or no effect on policy swing. The conclusion is that the preferences of veto players, but not party control of the government, have a substantial impact on gridlock in the United States.

26 Krehbiel’s model is likely to be acameral, rather than unicameral, because of the fictitious juxtaposition of the Senate filibuster pivot and the override, including a potential House override, pivot.

27 Poole and Rosenthal, Congress; and Poole, Spatial Models of Parliamentary Voting.

28 In actual congresses, a pivot represents ideal points of a veto player in dimension 1 and another veto player in dimension 2. Imagine a Southern Democrat who is pivotal in the economic dimension but extremely conservative in the social dimension. Even if she opposes a centrist bill on an exclusively social issue, liberals and moderates could support and pass the bill. This exemplifies that she is not a pivot in the social dimension. Thus, different legislators assume veto power in Dimension 1 and Dimension 2 separately. When legislation involves both economic and social issues with considerable importance, both pivots in Dimension 1 and Dimension 2 maintain veto power, hence decreasing the possibility of a passage. This would increase the necessity of moderating the bill. See Tsebelis, Veto Players, pp. 501.

29 For instance, when an ideal point of a bill is outside a liberal veto player’s indifference curve, the measure is likely to move the status quo away from the veto player and from the members who are more liberal than her. Thus, when a veto player opposes a bill, adjacent members with more extreme preferences are likely to oppose the measure as well.

30 In a sharp contrast, majority-rule spatial voting games are likely to result in unpredictable and unstable voting outcomes. When there is no one alternative that can defeat other alternatives, there is always an incentive for a new majority coalition to form and defeat the present status quo. See Richard D. McKelvey, ‘Intransitivities in Multidimensional Voting Models and Some Implications for Agenda Control’, Journal of Economic Theory, 12 (1976), 47282; Richard D. McKelvey, ‘General Conditions for Global Intransitivities in Formal Voting Models’, Econometrica, 47 (1979), 1085112; and Norman Schofield, ‘The Theory of Dynamic Games’, Review of Economic Studies, 45 (1978), 575–94.

40 There have been debates about a potential bias in the various selection methods of important laws. For bias in the selection of important laws by Mayhew, see Kelly, ‘Divided We Govern?’ and William Howell, Scott Adler, Charles Cameron and Charles Riemann, ‘Divided Government and the Legislative Productivity of Congress, 1945-1994’, Legislative Studies Quarterly, 25 (2000), 285–312. As for bias in laws selected by the ADA, see James M. Snyder Jr, ‘Artificial Extremism in Interest Group Ratings’, Legislative Studies Quarterly, 17 (1992), 319–45; Michael C. Herron, ‘Artificial Extremism in Interest Group Ratings and the Preferences versus Party Debate’, Legislative Studies Quarterly, 24 (1999), 525–42; and Tim Groseclose, Steven Levitt and James M. Snyder Jr, ‘Comparing Interest Group Scores across Time and Chambers: Adjusted ADA Scores for the U.S. Congress’, American Political Science Review, 93 (1999), 33–50. In contrast to the aforementioned scholars, Krehbiel contends that the bias is minimal and has no effect on the inference of the legislators’ preferences; see Keith Krehbiel, ‘Deference, Extremism, and Interest Group Ratings’, Legislative Studies Quarterly, 19 (1994), 61–77. Also, several scholars have found that the ADA ratings are very similar to other interest group ratings and roll-call ratings; see Poole and Rosenthal, Congress; and Brady and Volden, Revolving Gridlock, pp. 116–20. Brady and Volden calculate the average scores of eighteen interest-group ratings for the legislators. The average ratings are greatly correlated with the sole ADA ratings. This indicates that interest groups select similar laws. Poole and Rosenthal find that their dw-nominate scores, which are measured based upon the members’ votes on roll calls, are highly related to the ADA scores. In my study, the ADA measure of the change in policy output shows a significant correlation (r = 0.65) with the MWC measure.

41 ADA change = ADA policy outputt−ADA policy outputt −1.

42 MWC change=.

43 As for the filibuster pivot before 1975, the 34th and 67th percentile legislator under Republican and Democratic presidency, respectively.

44 Optimal Classification (OC) is a non-parametric scaling method with an assumption of legislators with single-peaked preferences in Euclidean space. The OC scale produces ideal points and cutting planes for the roll-call votes that maximize the number of correctly classified voting decisions. Just as the dw-nominate scores, the OC scores range from −1 to +1 and are comparable among different Congresses. In addition, the OC scores in the House and the Senate are comparable. Poole places the House and Senate in the same space based upon the ideal points of the legislators who served in both the House and Senate. See Poole, Spatial Models of Parliamentary Voting, pp. 192–5.

48 As I noted in the previous section, the exploration of the impact of divided government in conditional terms with intra-party and inter-party homogeneity, or with the size of the party, is not an appropriate test for party control of the government. If party control matters, divided government should cause gridlock without any interactive mutation. The influence of divided government in conditional terms with the alignment of legislators’ preferences indicates the influence of individual legislators’ preference rather than party control of the government.

50 For the variables of Binder’s and Edwards’s measurements, which are ratio variables constructed from grouped data, I model variation with the weighted least squares logistic regression for grouped data (Glogit). The Glogit function accounts for the variation in the denominator for the ratio variables.

51 Mayhew, Divided We Govern, 19462000, 2nd edn, pp. 207–15.

52 By examining congresses from 1946 to 1986, Kelly finds a moderate impact of divided government.

53 In contrast, Binder finds an impact of divided government regardless of the salience level of legislative agendas. See Binder, Stalemate, pp. 68–73.

54 For both the two variables, the Augmented Dickey–Fuller test and Phillips–Perron test strongly reject the hypothesis of a unit root.

55 The variables of winset and divided government are not related (r = 0.17).

57 The MWC policy change is the difference between the MWC score in the examined congress and the status quo. While the value of the status quo is partially involved in the calculation for the dependent variable, there is a possibility that the status quo could also influence the winset area. The winset area could be potentially affected by the veto players’ propinquity to the status quo, as well as the veto players’ proximity among themselves. However, a preliminary test confirmed that the variables of the MWC policy change and the winset size are not related to the values of the status quo in Dimension 1 or Dimension 2. Thus, the policy shift in the MWC measure and the area of the winset are not confounded with the value of the status quo.
