The candidates are not nonpartisan. They are required to be a registered voter and therefore have identified with one of the political parties or labeled themselves as "independent" or "unaffiliated." According to the Maryland Manual Online, "As of 2015, four political parties were recognized by the State Board of Elections: the Democratic Party, the Green Party, the Libertarian Party, and the Republican Party. The Americans Elect Party, the Constitution Party of Maryland, the Independent Party of Maryland, the Populist Party, and the Reform Party no longer are recognized as political parties by the State Board." This selection itself tells a voter something about the candidate.
