In August 2009, Cardin was criticized for using Baltimore Police Department resources to perform a marriage proposal prank. Cardin was using a friend's boat when police boarded the boat as a Foxtrot helicopter hovered above the boat. According to the Baltimore Sun, Cardin's girlfriend thought she was going to be arrested when Cardin proposed to her. After the issue became public, Delegate Cardin promised to reimburse the City of Baltimore for the costs incurred. Cardin paid $300 to the Baltimore Police Department to cover the costs and donated $1,000 to the city's mounted unit.[13] The Baltimore Police Department launched an internal affairs investigation into the marriage proposal incident.[14] In November 2009, a police sergeant was charged with misconduct in connection with the prank.[15]
During the Democratic primary, Cardin was criticized for benefiting from political nepotism after campaigning with his uncle Ben Cardin,[19][20] for misusing Baltimore Police Department resources in a stunt wedding proposal, missing 75 percent of committee votes during the 2014 legislative session, and touting an endorsement from Ski Money, a Baltimore-based rapper who had been indicted on human trafficking charges in Baltimore County.[21][22] Following the Democratic primary election, he called these criticisms "the most negative smear campaign in a Democratic Party primary in Maryland's modern history".[4][23]
In June 2014, Cardin filed a report with the Maryland State Board of Elections against state senator Lisa Gladden and state delegate Maggie McIntosh, both supporters of Brian Frosh, accusing the lawmakers of "verbally harassing" one of his campaign volunteers. Both legislators denied Cardin's accusations, with McIntosh saying that she had not confronted any Cardin supports while canvassing and Gladden saying that she was never at the polling place described in the report.[24]
Polling ahead of the primary election showed Cardin leading other Democratic challengers Frosh and Aisha Braveboy, but with a majority of voters saying that they were undecided.[25][26] He was defeated in the Democratic primary by state senator Brian Frosh on June 24, 2014, and conceded to Frosh the day after the election.[27] Following his defeat, Cardin worked as a lobbyist.[28]
