Within days, some of Kennedy's aides were urging McGovern to run in his place; their antipathy toward McCarthy and ideological opposition to Humphrey made them unwilling to support either candidate. McGovern delayed making a decision, making sure that Bobby's brother Ted Kennedy did not want to enter, and with his staff still concerned about the senator's own reelection prospects. Indeed, McGovern's voting had changed during 1968, with his ADA rating falling to 43 as he sought more middle-of-the-road stances. In late July, McGovern's decision became more complicated when his daughter Teresa was arrested in Rapid City on marijuana possession charges. She had led a troubled life since her teenage years, developing problems with alcohol and depression and suffering the consequences of a relationship with an unstable neighborhood boy. On the basis of a recently enacted strict state drugs law, Terry now faced a minimum five-year prison sentence if found guilty. McGovern was also convinced that the socially conservative voters of South Dakota would reject him owing to his daughter's arrest. Charges against her were subsequently dropped because of an invalid search warrant.
