Notable personal detailsMark Edmund Johnston is a Nebraska Democrat who filed with the FEC as a candidate for the U.S. House in Nebraska’s 2nd Congressional District in the 2026 cycle. He is a retired eye surgeon/ophthalmologist based in Omaha. In late July 2025, he publicly withdrew from the Democratic primary field, citing fundraising difficulties, and said he planned to remain involved with the Democratic Party.
The candidate supports defending and preserving programs like Medicaid and food assistance and favors fixing rather than defunding existing public-health safety-net programs. The campaign emphasizes protecting access to public health and safety and lists women’s health and public health among policy priorities.
The candidate has made public campaign materials referencing immigration and has a recorded legislative vote supporting authorization of prenatal care for undocumented immigrants; however there is no clear, detailed policy platform on border security or comprehensive immigration reform available in the located sources.
The candidate has a legislative record supporting restrictions on abortion, including voting for a law related to a 72-hour waiting period prior to an abortion. He has received mixed-to-supportive ratings from anti-abortion groups in past scorecards.
Mark Johnston is in the news because Nebraska held primary elections in the state’s 2nd Congressional District ahead of the 2026 U.S. House race. The coverage focuses on campaign spending and how candidates positioned themselves in the contest. It does not report the final general election outcome or any later result for Johnston.
