The Implications Of Polarization

The Implications of Polarization

The past thirty years have brought a dramatic change in the relationship between the two parties as fewer conservative Democrats and liberal Republicans have been elected to office. As political moderates, or individuals with ideologies in the middle of the ideological spectrum, leave the political parties at all levels, the parties have grown farther apart ideologically, a result called party polarization. In other words, at least organizationally and in government, Republicans and Democrats have become increasingly dissimilar from one another. In the party-in-government, this means fewer members of Congress have mixed voting records; instead they vote far more consistently on issues and are far more likely to side with their party leadership.

It also means a growing number of moderate voters aren’t participating in party politics. Either they are becoming independents, or they are participating only in the general election and are therefore not helping select party candidates in primaries.

The number of moderates has dropped since 1973 as both parties have moved toward ideological extremes.

What is most interesting about this shift to increasingly polarized parties is that it does not appear to have happened as a result of the structural reforms recommended by APSA. Rather, it has happened because moderate politicians have simply found it harder and harder to win elections. There are many conflicting theories about the causes of polarization, some of which we discuss below. But whatever its origin, party polarization in the United States does not appear to have had the net positive effects that the APSA committee was hoping for. With the exception of providing voters with more distinct choices, positives of polarization are hard to find. The negative impacts are many. For one thing, rather than reducing interparty conflict, polarization appears to have only amplified it. For example, the Republican Party (or the GOP, standing for Grand Old Party) has historically been a coalition of two key and overlapping factions: pro-business rightists and social conservatives. The GOP has held the coalition of these two groups together by opposing programs designed to redistribute wealth (and advocating small government) while at the same time arguing for laws preferred by conservative Christians. But it was also willing to compromise with pro-business Democrats, often at the expense of social issues, if it meant protecting long-term business interests.

Recently, however, a new voice has emerged that has allied itself with the Republican Party. Born in part from an older third-party movement known as the Libertarian Party, the Tea Party is more hostile to government and views government intervention in all forms, and especially taxation and the regulation of business, as a threat to capitalism and democracy. It is less willing to tolerate interventions in the market place, even when they are designed to protect the markets themselves. Although an anti-tax faction within the Republican Party has existed for some time, some factions of the Tea Party movement are also active at the intersection of religious liberty and social issues, especially in opposing such initiatives as same-sex marriage and abortion rights. The Tea Party has argued that government, both directly and by neglect, is threatening the ability of evangelicals to observe their moral obligations, including practices some perceive as endorsing social exclusion.

Although the Tea Party is a movement and not a political party, 86 percent of Tea Party members who voted in 2012 cast their votes for Republicans. Some members of the Republican Party are closely affiliated with the movement, and before the 2012 elections, Tea Party activist Grover Norquist exacted promises from many Republicans in Congress that they would oppose any bill that sought to raise taxes. The inflexibility of Tea Party members has led to tense floor debates and was ultimately responsible for the 2014 primary defeat of Republican majority leader Eric Cantor and the 2015 resignation of the sitting Speaker of the House John Boehner. In 2015, Chris Christie, John Kasich, Ben Carson, Marco Rubio, and Ted Cruz, all of whom were Republican presidential candidates, signed Norquist’s pledge as well.

Vying for the Republican nomination, 2016 presidential candidates Ted Cruz (a) and John Kasich (b), like many other Republicans, signed a pledge not to raise taxes if elected.

Movements on the left have also arisen. The Occupy Wall Street movement was born of the government’s response to the Great Recession of 2008 and its assistance to endangered financial institutions, provided through the Troubled Asset Relief Program, TARP. The Occupy Movement believed the recession was caused by a failure of the government to properly regulate the banking industry. The Occupiers further maintained that the government moved swiftly to protect the banking industry from the worst of the recession but largely failed to protect the average person, thereby worsening the growing economic inequality in the United States.

While the Occupy Movement itself has largely fizzled, the anti-business sentiment to which it gave voice continues within the Democratic Party, and many Democrats have proclaimed their support for the movement and its ideals, if not for its tactics. Champions of the left wing of the Democratic Party, however, such as presidential candidate Senator Bernie Sanders and Massachusetts Senator Elizabeth Warren, have ensured that the Occupy Movement’s calls for more social spending and higher taxes on the wealthy remain a prominent part of the national debate. Their popularity, and the growing visibility of race issues in the United States, have helped sustain the left wing of the Democratic Party. Bernie Sanders’ presidential run made these topics and causes even more salient, especially among younger voters. To date, however, the Occupy Movement has had fewer electoral effects than has the Tea Party. Yet, as manifested in Sanders’ candidacy, it has the potential to affect races at lower levels in the 2016 national elections.

Unfortunately, party factions haven’t been the only result of party polarization. By most measures, the U.S. government in general and Congress in particular have become less effective in recent years. Congress has passed fewer pieces of legislation, confirmed fewer appointees, and been less effective at handling the national purse than in recent memory. If we define effectiveness as legislative productivity, the 106th Congress (1999–2000) passed 463 pieces of substantive legislation (not including commemorative legislation, such as bills proclaiming an official doughnut of the United States). The 107th Congress (2000–2001) passed 294 such pieces of legislation. By 2013–2014, the total had fallen to 212.

Perhaps the clearest sign of Congress’ ineffectiveness is that the threat of government shutdown has become a constant. Shutdowns occur when Congress and the president are unable to authorize and appropriate funds before the current budget runs out. This is now an annual problem. Relations between the two parties became so bad that financial markets were sent into turmoil in 2014 when Congress failed to increase the government’s line of credit before a key deadline, thus threatening a U.S. government default on its loans. While any particular trend can be the result of multiple factors, the decline of key measures of institutional confidence and trust suggest the negative impact of polarization. Public approval ratings for Congress have been near single digits for several years, and a poll taken in February 2016 revealed that only 11 percent of respondents thought Congress was doing a “good or excellent job.” President Obama’s average approval rating has remained low, despite an overall trend of economic growth since the end of the 2008 recession. Typically, economic conditions are a significant driver of presidential approval, suggesting the negative effect of partisanship on presidential approval.
