Beginning in the 1950s and early 1960s, Hall began participating in local politics, serving on several boards and commissions in Brookline.

Hall's career in statewide politics began in 1970 when she was elected to the New Hampshire House of Representatives as a member of the Republican Party.

[2][4] During World War II, she helped manufacture vacuum tubes for radar equipment, and her father served as a special assistant to Frank Knox, the United States Secretary of the Navy.

[1][5] On May 27, 1944, she married Sidney Leavitt Hall, an engineer from Concord, New Hampshire, leaving her job at Western Electric to join her husband in Ohio, where he was undergoing training with the United States Air Force in order to fight in World War II.

[1][6] However, the war ended before he was sent overseas, and in 1948, the couple moved to Brookline, New Hampshire, a town of 800 people in Hillsborough County.

[11][12] In 1968, Hall was awarded a grant by the Research Corporation for Science Advancement in order to start an experimental "Mathematics Learning Laboratory" at her school.

[3] Later that year, Hall again ran for the Brookline board of selectmen to succeed the retiring Grover C. Farwell, defeating two candidates to win a three-year term as selectman.

[8] In 1970, Hall ran for the New Hampshire House of Representatives in Hillsborough County's 13th district as a member of the Republican Party.

[10] She was recruited to run by Governor Walter R. Peterson Jr.[1] Hall and fellow Republican Daniel Brocklebank were elected with 43% and 41% of the vote, respectively.

[27] In 1972, Hall ran for re-election in Hillsborough County's 12th district,[a] and was elected unopposed alongside fellow Republican Jack Boyd.

[29][30] In 1974, Hall ran for the 12th district of the New Hampshire Senate, running to replace retiring Republican incumbent Frederick A.

[34][37] During the general election campaign, Rock was heavily supported by William Loeb III, the publisher of the Manchester Union Leader, an influential conservative newspaper.

[42] In 1975, Hall became the chairman of the New Hampshire branch of Common Cause, a lobbying group that opposes corruption and promotes campaign finance reform.

[49] In November 1980, Rock, who had still serving as the state senator for the 12th district, died of cancer just three days after winning re-election.

[54] Stabile would go on to defeat Democratic state representative Selma Pastor and independent candidate Mark Knox, a Nashua alderman, in the special election.

[52][53] In 1982, Hall ran for the 11th district of the New Hampshire Senate to replace retiring Republican incumbent Arthur Mann.

[56] However, Hall won the Democratic nomination as a write-in candidate, receiving 199 votes compared to White's 81 and Amidon's 55.

[70] Hall also praised Richard Lugar during the 1996 Republican Party presidential primaries, supporting his tax policy and stating that he seemed honest.

[74] Hall, who was 83 at the time, was sitting in a chair outside the designated area for protestors, and was close to the presidential motorcade route.

Her main opponent was Raymond Buckley, the vice chair of the state party and an executive member of the Democratic National Committee.

[79] During the campaign, Buckley, who was considered to be the frontrunner, was falsely accused of possessing child pornography by former state representative Steve Vaillancourt, who had been a former friend of his.

[83] A third candidate, former state house Democratic Leader Jim Craig, withdrew following Buckley's exoneration, but remained on the ballot.

[80][84] In 2008, Hall again gained national prominence for introducing a bill in the New Hampshire House of Representatives which would petition the United States Congress to introduce articles to impeach President Bush and Vice President Dick Cheney for high crimes and misdemeanors relating to the Iraq War.

[88][89] Hall's bill was supported by Pentagon Papers leaker Daniel Ellsberg, former US attorney general Ramsey Clark, and former director of the Strategic Defense Initiative Robert M.

That year, Hall ran as an independent candidate for the New Hampshire House of Representatives in Hillsborough County's 5th district.

She served as the first president of Milford Regional Counseling Services in the 1970s, and later founded Harbor Homes, an organization that provides transitional housing for people with mental illness.

[103] Hall sponsored a similar bill in 1979, which would have imposed a tax ranging from $25 to $9,000 a year on businesses in order to fund litter control and recycling.

[108] In 2007, Hall supported legislation pushed by the Regional Greenhouse Gas Initiative which would "reduce carbon pollution from power plants, lower energy bills and strengthen our economy".

[110] In 1971, Hall sponsored legislation which would establish a volunteer corps to provide assistance and counseling to minors who violated the law.

The program would provide matching funds for college students: the state would allocate 25 cents for every dollar given by a private scholarship.
