The looser partisanship of the period was mostly the result of racism and its complex role in the politics of the time. The legacy of the Civil War had made the Democrats the party of southern white supremacists, but the legacy of the New Deal had also made them the party of northern liberals and many urban African Americans. These latter constituencies were demanding federal intervention in southern affairs to secure the rights of southern blacks. At the same time, many members of the GOP—the traditional home of black voters and the party of racial progress in many states—were resisting these demands, which struck them as violating the principle of a modest federal government.
The result was a muddle. Nearly every congressional representative from the South was a Democrat and an opponent of civil rights, irrespective of his or her views about anything else. So while most Democrats were to the left of Republicans on economic and foreign-policy issues, many were more conservative than the average Republican on matters of race. Racial liberals and racial conservatives could be found in both parties.
Since the 1970s, however, the significance of civil-rights conflicts in American elections has declined sharply. As older representatives left Congress in the 1980s, political divisions became cleaner. Ideologically moderate politicians have not disappeared, but relatively conservative Democrats like Senators Ben Nelson and Mary Landrieu are, on most issues, now to the left of relatively liberal Republicans such as Susan Collins and Olympia Snowe. The meet-in-the-middle overlap is gone.
From a journalistic point of view, the resulting system is tragically dull. Legislative outcomes become a simple matter of vote-counting: either a party has a majority or it doesn’t. There’s little room for journalistic sleuthing, and what stories there are to tell lack the color and drama of, say, Charlie Wilson’s War, in which an extremely hawkish Democratic congressman was able to persuade his party’s leadership to back a massive covert war in Afghanistan.
For veteran Washington hands—wheelers and dealers in the lobbying game or at the major interest groups—the new system is worse than dull. It’s emasculating. This is why political elites find polarization so distasteful. In a polarized world, elections and procedural rules largely determine policy outcomes; there’s little room for self-styled players to construct coalitions on the fly, and enhance their own power in the process. The growth in the lobbying industry might seem to belie the point, but consider Tom DeLay’s post-1994 “K Street Project”—which pressured lobbying firms who wanted access on the Hill to hire more Republicans—or the swing of the pendulum back after the Democratic takeover in 2006. Power in Congress is firmly in the hands of the party leadership; lobbyists become less powerful, not more, in a polarized system.
But for voters, the boring new ways can be looked at in another way—they’re straightforward. Elections have a predictable and easy-to-understand relationship to government action. Electing a Democrat means, on the margin, more spending on the federal safety net and more government regulation, while electing a Republican produces policies more favorable to business interests. You don’t necessarily get everything you want (ask any liberal disappointed by the continued flow of funds for the Iraq War), but at least on domestic measures, things move predictably.
