Jefferson won the national election in a landslide over Pinckney, who received electoral votes from Connecticut and Delaware, in addition to the two Maryland districts. Maryland was one of three states where electors were chosen by popular vote which the Federalists seriously contested. Although a clandestine gathering of Federalist members of Congress had nominated Pinckney in February, the Federalist electors were formally unpledged. The defeat of the Federalist ticket in Massachusetts and New Hampshire made Maryland's two Federalist districts the only popular vote constituencies to oppose Jefferson's re-election.[4]
Maryland chose 11 electors from nine electoral districts—seven single-member districts and two plural districts electing two electors each. Nineteenth-century election laws required voters to elect the members of the Electoral College individually, rather than as a block. This sometimes resulted in small differences in the number of votes cast for electors pledged to the same presidential nominee, if some voters did not vote for all the electors nominated by a party.[5] The following table calculates the sum of all votes in the single-member districts and the votes for the leading Democratic-Republican and Federalist candidates in each plural district to give an approximate sense of the statewide popular vote.

In counties where voters selected more than one elector, this table compares the votes for the leading elector pledged to each ticket by county and county subdivision. It therefore differs slightly from the state and district tables, which compare the votes for the leading electors by district.
