By the early 21st century, political pundits were routinely dividing the United States into red and blue states, whose assigned colours not only indicated which political party was locally dominant but also signified the supposed prevalence of a set of social and cultural values. According to the received wisdom, the red states—generally located in the South, West, and Lower Midwest—were Republican, conservative, God-fearing, “pro-life” (on the issue of abortion), small-town and suburban, opposed to big government and same-sex marriage, and enamoured of NASCAR. The blue states—found mostly on the coasts, in the Northeast, and in the Upper Midwest—were similarly reductively characterized as Democratic, liberal, secular, politically correct, “pro-choice” (on abortion), urban, and connoisseurs of wine, cheese, and latte.
Both the Democratic and Republican parties select their candidates for office through primary elections. Traditionally, individuals worked their way up through the party organization, belonging to a neighbourhood party club, helping to raise funds, getting out the vote, watching the polls, and gradually rising to become a candidate for local, state, and—depending on chance, talent, political expediency, and a host of other factors—higher office. Because American elections are now more heavily candidate-centred rather than party-centred and are less susceptible to control by party bosses, wealthy candidates have often been able to circumvent the traditional party organization to win their party’s nomination.

Security
National security
The September 11 attacks of 2001 precipitated the creation of the Department of Homeland Security, which is charged with protecting the United States against terrorist attacks. The legislation establishing the department—the largest government reorganization in 50 years—consolidated much of the country’s security infrastructure, integrating the functions of more than 20 agencies under Homeland Security. The department’s substantive responsibilities are divided into four directorates: border and transportation security, emergency preparedness, information analysis and infrastructure protection, and science and technology. The Secret Service, which protects the president, vice president, and other designated individuals, is also under the department’s jurisdiction.

(A related force, the Coast Guard, is under the jurisdiction of the Department of Homeland Security.) Conscription was ended in 1973, and since that time the United States has maintained a wholly volunteer military force; since 1980, however, all male citizens (as well as immigrant alien males) between 18 and 25 years of age have been required to register for selective service in case a draft is necessary during a crisis. The armed services also maintain reserve forces that may be called upon in time of war. Each state has a National Guard consisting of reserve groups subject to call at any time by the governor of the state.
Because a large portion of the military budget, which generally constitutes about 15 to 20 percent of government expenditures, is spent on matériel and research and development, military programs have considerable economic and political impact. The influence of the military also extends to other countries through a variety of multilateral and bilateral treaties and organizations (e.g., the North Atlantic Treaty Organization) for mutual defense and military assistance. The United States has military bases in Africa, Asia, Europe, and Latin America.
The National Security Act of 1947 created a coordinated command for security and intelligence-gathering activities. The act established the National Security Council (NSC) and the Central Intelligence Agency (CIA), the latter under the authority of the NSC and responsible for foreign intelligence. The National Security Agency, an agency of the Department of Defense, is responsible for cryptographic and communications intelligence. The Department of Homeland Security analyzes information gathered by the CIA and its domestic counterpart, the Federal Bureau of Investigation (FBI), to assess threat levels against the United States.

Domestic law enforcement
Traditionally, law enforcement in the United States has been concentrated in the hands of local police officials, though the number of federal law-enforcement officers began to increase in the late 20th century. The bulk of the work is performed by police and detectives in the cities and by sheriffs and constables in rural areas. Many state governments also have law-enforcement agencies, and all of them have highway-patrol systems for enforcing traffic law.
The investigation of crimes that come under federal jurisdiction (e.g., those committed in more than one state) is the responsibility of the FBI, which also provides assistance with fingerprint identification and technical laboratory services to state and local law-enforcement agencies. In addition, certain federal agencies—such as the Drug Enforcement Administration of the Department of Justice and the Bureau of Alcohol, Tobacco, and Firearms of the Department of the Treasury—are empowered to enforce specific federal laws.
Health and welfare
Despite the country’s enormous wealth, poverty remains a reality for many people in the United States, though programs such as Social Security and Medicare have significantly reduced the poverty rate among senior citizens. In the early 21st century, more than one-tenth of the general population—and about one-sixth of children under 18 years of age—lived in poverty. About half the poor live in homes in which the head of the household is a full- or part-time wage earner. Of the others living in poverty, many are too old to work or are disabled, and a large percentage are mothers of young children. The states provide assistance to the poor in varying amounts, and the United States Department of Agriculture subsidizes the distribution of low-cost food and food stamps to the poor through the state and local governments. Unemployment assistance, provided for by the 1935 Social Security Act, is funded through worker and employer contributions.

Increasing public concern with poverty and welfare led to new federal legislation beginning in the 1960s, especially the Great Society programs of the presidential administration of Lyndon B. Johnson. Work, training, and rehabilitation programs were established in 1964 for welfare recipients. Between 1964 and 1969 the Office of Economic Opportunity began a number of programs, including the Head Start program for preschool children, the Neighborhood Youth Corps, and the Teacher Corps. Responding to allegations of abuse in the country’s welfare system and charges that it encouraged dependency, the federal government introduced reforms in 1996, including limiting long-term benefits, requiring recipients to find work, and devolving much of the decision making to the states.
