Maryland's 8th congressional district is concentrated entirely in Montgomery County. Adjacent to Washington, D.C., the 8th district takes in many of the city’s wealthiest inner-ring suburbs, including Bethesda, Chevy Chase, and Potomac. It also includes several more economically and racially diverse communities, the most populous of which are Rockville and Silver Spring. With a median household income of $120,948, it is the ninth-wealthiest congressional district in the nation. The 8th district also has the eighth-highest share of residents with at least a bachelor's degree, at 63.9%. Those above-average numbers are largely due to the substantial presence of the federal government in nearby Washington, where thousands of the 8th district’s residents commute to work on a daily basis. Several federal agencies are likewise located within the 8th district, including the Food and Drug Administration, the National Institutes of Health, the Nuclear Regulatory Commission, and the Walter Reed National Military Medical Center. Two Fortune 500 companies are headquartered in the district: Lockheed Martin and Marriott International.Politically, the district is heavily liberal. It has consistently sent Democratic representatives to Congress by wide margins since 2002. In 2020, Joe Biden won nearly 80% of its vote. Democrat Jamie Raskin has represented the seat since 2017.

The Darnestown Presbyterian Church dates back to the 1850s, and is located in Darnestown, Maryland. It is a Presbyterian Church (USA) congregation and a member of the National Capital Presbytery. Behind the church building is a cemetery with the graves of many of the early settlers of western Montgomery County, and some of the local roads and villages are namesakes of members of those pioneering families. The first European landowner in the Darnestown area was Ninian Beall, who settled around 1749. Some Beall family members are buried in the church cemetery. Construction of the church began in 1855, after community leader John L. DuFief donated three acres (1.2 ha) of land. The cornerstone was laid on September 14, 1856, and a small vernacular frame building with no steeple and no stained-glass windows was constructed. The completed church was dedicated on May 22, 1858. In 1897, a bell tower and parlor were added. Improvements in 1952 and 1953 included expansion of the building, stained glass windows, and a Hammond organ. Today (2022), the church has about 350 members and is active in the community. The church and cemetery are located close to the intersection of Darnestown Road and Turkey Foot Road.

North Potomac is a census-designated place and unincorporated area in Montgomery County, Maryland, United States. It is located less than 5 miles (8.0 km) north of the Potomac River, and is about 20 miles (32 km) from Washington, D.C. It has a population of 23,790 as of 2020.The region's land was originally used for growing tobacco, which was replaced by wheat and dairy farming after the soil became depleted. The Chesapeake and Ohio Canal was used by local farmers to ship their grain (or flour made from the grain at the local mills), and two former canal locks are located less than 5 miles (8.0 km) away in the Chesapeake and Ohio Canal National Historical Park. In addition, infrastructure remains for what was one of the state's leading dairy farms during the first half of the 20th century. North Potomac did not get an identity of its own until 1989, when the United States Post Office allowed the use of the North Potomac name for what is mostly a collection of housing sub-divisions, farms, and wooded parks. The United States Census Bureau listed a North Potomac in 1970 but not 1980. In 2000, it began recognizing North Potomac as a census designated place. Today, the community benefits from its proximity to workplaces such as the Shady Grove Hospital area and the I-270 Technology Corridor. Washington, D.C. is accessible by automobile or public transportation. The median household income is nearly $160,000, and nearly half of the eligible residents have a graduate or professional degree.

Travilah is a United States census-designated place and an unincorporated area in Montgomery County, Maryland. It is 17.28 square miles (44.8 km2) located along the north side of the Potomac River, and surrounded by the communities of Potomac, North Potomac, and Darnestown—all census-designated places. It had a population of 11,985 as of the 2020 census.Within the Travilah census-designated place at the intersection of what are now Travilah Road and Glen Road, the small rural community of Travilah existed in the late 1800s and early 1900s. The community had its own post office, general store, school, town hall, church, and a few homes. The crossroads was popular with area farmers because it was close to the Chesapeake and Ohio Canal (C&O Canal) and at least two mills. The name Travilah comes from Travilah Clagett, who was the community's first postmaster in 1883. In 2000, the United States Census Bureau began recognizing the area around the original Travilah crossroads community as a census designated place. Much of this tranquil community is simply large homes on large tracts of land with numerous parks and nature preserves mixed in. The community is within driving-distance of Washington, D.C., and the I-270 Technology Corridor. Travilah has a median household income of about $235,000.

Darnestown is a United States census-designated place (CDP) and an unincorporated area in Montgomery County, Maryland. The CDP is 17.70 square miles (45.8 km2) with the Potomac River as its southern border and the Muddy Branch as much of its eastern border. Seneca Creek borders portions of its north and west sides. The Travilah, North Potomac, and Germantown census-designated places are adjacent to it, as is the city of Gaithersburg. Land area for the CDP is 16.39 square miles (42.4 km2). As of the 2020 census, the Darnestown CDP had a population of 6,723, while the village of Darnestown is considerably smaller in size and population. Downtown Washington, D.C. is about 22 miles (35 km) to the southeast. Within the Darnestown census-designated place at the intersection of what is now Darnestown Road and Seneca Road, the small village of Darnestown has existed since about 1800. The community had a population of 200 in 1878. The name Darnestown comes from William Darne, who owned the most land in the area at the beginning of the 19th century when the community post office opened. Settlement in the area began around 1750, and the tiny community was called Mount Pleasant, and then Darnes, before the name Darnestown began being used. The community thrived in the 19th century during the golden years of the Chesapeake and Ohio Canal, as the improved transportation facilities offered area farmers access to more markets. In the 1880 census, the United States Census Bureau began using a Minor Civil Division (MCD) category for aggregating populations, and the new Darnestown district had about 1,500 people. Growth stopped late in the 19th century when a new railway bypassed the community. In the 1960s, affluent families began buying Montgomery County farmland for new housing and equestrian purposes. Today, many Darnestown CDP residents are wealthy and live in large homes on large lots, which is reflected in their high average income and low housing density. The median household income is nearly $228,000, and 73 percent of residents aged 25 years or more have at least a bachelor's degree or higher. The community benefits from its proximity to workplaces such as the Shady Grove Hospital area and the I-270 Technology Corridor. Washington is accessible by automobile or public transportation. Beginning with the 2000 census, the Census Bureau created a Darnestown census-designated place.
