Elections In 2014, Lehman voted to approve an amendment to the county's charter that would give members of the county council another four-year term opposed to only two consecutive terms. Lehman opposed legislation introduced by delegate
Dereck E. Davis during the 2019 legislative session that would set up a public financing system for county campaigns in the 2026 election cycle, saying that the 2026 timeline was too far away. She also voted against legislation that would lift the ban on developer contributions in county political races.
Environment In 2012, Lehman promoted legislation introduced by delegate
Barbara Frush that would allow the Prince George's County council to require shoppers to pay for disposable bags. The bill was unexpectedly killed in the House Environmental Matters Committee, where it received a 12–11 vote to kill the bill. Lehman introduced legislation in the 2019 legislative session that would have set strict standards for recycling crumb rubber-modified turf. She withdrew the bill later in the session, but planned to reintroduce it in the next legislative session. Lehman received a score of 100 percent on the Maryland League of Conversation Voters' 2021 legislative scorecard.
Housing Lehman introduced legislation in the 2022 legislative session that would require landlords to prove they are in compliance with local laws and state statutes when they file a failure to pay rent case.
Taxes Lehman introduced legislation in the 2020 legislative session that would require corporate combined tax reporting. The bill passed the House of Delegates but did not receive a vote in the
state senate. She also cosponsored legislation that would create a multi-state compact to end corporate tax breaks aimed at getting businesses to move across state lines.
Transportation As a councilwoman, Lehman was vocally opposed to a proposed high-speed maglev train that would run from
Washington, D.C., to
Baltimore, citing concerns over the train's environmental impact, cost, and economic potential. In the 2018 legislative session, she filed legislation that would have provided state income and property tax credits to companies affected by the maglev's construction. She said that she would oppose a repeal of existing laws that give Eastern Shore counties the right to block state-backed toll facilities. ==Personal life==
