St. Mary's Aftermath After the vote, both candidates claimed victory, before the official count declared O'Conor the winner by a margin of 2,232 out of more than 470,000 votes cast. On December 10, 1946, Markey requested the U.S. Senate
Special Committee to Investigate Senatorial Campaign Expenditures (now controlled by Republicans after their landslide victories in the 1946 elections) conduct a recount in
Baltimore City and
Montgomery County, which had used electronic
voting machines. The committee completed its full recount of the state in January 1948 and concluded that O'Conor had secured a 1,624-vote majority. ==See also==
