Maryland Republicans hold their state convention in Baltimore amidst hostile crowds
The Maryland State Republican Convention was held in Baltimore with around thirty delegates attending. From the very start the meeting was plagued by disruptions from hostile crowds, despite the best efforts of the police. Abandoning their original meeting place, the delegate reassembled in a commercial office and chose representatives for the national convention in Chicago before adjourning. (By John Osborne)
