Calvin Young, a 27-year-old engineer and Harvard Business School graduate, on Tuesday said he was filing paperwork to run as a Democrat for mayor of Baltimore -- bringing the field of candidates to four.
Young, a native of Baltimore who graduated from Poly and New York University, is a former city youth commissioner.
He will be competing against current Mayor Stephanie Rawlings-Blake and former Mayor Sheila Dixon, who have announced their campaigns.
Young would be the second candidate to officially file to run. The other is Mack Clifton, a minister and author who has written about the plight of homeless veterans in Baltimore.
Candidates have until Feb. 3 to file to run. The Democratic primary — which for decades has determined Baltimore's mayor — is April 26, just eight months from now.
Other candidates who have said they're seriously considering a run include State Sen. Catherine Pugh and City Councilman Carl Stokes.
