Montgomery County Council member Marc Elrich (D-At Large) has made his first formal move into the 2017 county executive race. On Feb. 22, the three-term incumbent filed with the Maryland Board of Elections declaring his intent to qualify for public funding under the county’s new campaign finance law.

Elrich, 67, who lives in Takoma Park, was widely expected to become a candidate. He joins council member George L. Leventhal (D-At Large), also of Takoma Park, as the second formally declared candidate. Leventhal has also filed to use public financing.

A third council member, council President Roger Berliner (D-Potomac-Bethesda), is likely to join the race. Two candidates from the private sector, wine retailer David Trone and health-care executive David Blair, both of Potomac, are also considering candidacies.

News of Elrich’s filing was first reported Wednesday by the Seventh State blog.
