African Americans are strongly Democratic; Latino voters often favor Democrats, although Cuban Americans, concentrated particularly in Florida, historically have tended to support the Republican Party. Asian Americans and Jewish Americans tend to vote Democratic, though many members of these groups support Republicans. Evangelical Christians have formed an important core of the Republican Party since the 1980s. White voters, particularly white males, have become strong Republican supporters since the 1980s. Republicans have also attracted working class voters who were long supporters of Democratic candidates, although union members still tend to favor Democrats.

How the Two Major Parties Differ
The parties' various policy positions are not etched in stone and can change over time. For example, historically Republicans have supported free trade, but in the early 21st century many Republican voters moved away from that position. Likewise, Democrats were once the party of segregation in the South but have become more closely aligned with policies supporting the civil rights of African Americans and other minority groups.
In broad policy areas, the two parties differ in the following ways:
- Governmental power: In general, Republicans believe that the national government should be less involved in citizens' lives and that many policy decisions should be left up to the states so that policy better reflects the unique needs and political position of the state's people. Democrats tend to favor more federal government involvement in American life to ensure consistent policies across the country. This debate affects policy making in any number of areas, from health care to gun control to education spending and standards.
- Economic policy: Because Republicans generally believe that less government is better, they think that taxes should be low for all taxpayers. They also favor low taxes on corporations, believing this will encourage them to invest in growth and innovation, which will, in turn, help the economy grow and provide for more jobs and higher wages. Democrats favor higher and progressive taxes on the wealthy and on corporations as an attempt to put the tax burden on those they think can more easily afford it. Republicans support a business-friendly government with minimal government regulation. Democrats favor government regulation of the economy in cases involving safety, health, and individual rights. Both parties have generally supported free trade since the second half of the 20th century, though critics on both the Democratic left and the Republican right have criticized free trade as being unfair to American companies and workers. Many Republicans shifted in the 2010s to favor policies aimed at protecting American industries from foreign competition through tariffs and other measures.
- Foreign policy: Republicans favor a strong foreign policy emphasizing national interests, and many accept unilateral American action abroad. Democrats tend to be more internationalist in outlook, urging that the United States join with allies in collective diplomacy.
- Domestic policy: Republicans oppose a government-funded health care for all, arguing that such an approach will inflate costs, diminish the quality of care, and reduce patients' freedom of choice. Democrats argue that a greater governmental role in the health insurance market can ensure greater access to high-quality health care for all people, regardless of income. On immigration, Democrats encourage exploring ways to open a path to citizenship for at least some of the more than 10 million undocumented immigrants living in the United States. Republicans endorse a far stricter approach, generally opposing any permanent legal status for immigrants who arrived in the United States illegally. While both parties support stronger border security, Republicans are typically in favor of stronger measures than Democrats. A significant share of Republicans favor less environmental regulation while Democrats tend to support more and stronger environmental regulations.
- Social issues: Abortion and LGBTQ rights have been the focus of fairly strong partisan differences. Democrats generally support the Supreme Court decision in Roe v. Wade (1973), which legalized abortion in a majority of cases. Republicans favor limits on abortion rights or, for many, laws banning abortions. Republicans also generally opposed the Supreme Court decision that legalized same-sex marriage (Obergefell v. Hodges ), while Democrats approved of the decision.
