Two supporters of arch-conservative Lyndon H. LaRouche who are running for Maryland state office said today that the success of Larouche-backed candidates in the Illinois Democratic primary Tuesday was a bellwether for 1986 elections in Maryland and the rest of the nation.

Debra Freeman, a member of LaRouche's National Democratic Policy Committee who is running for the U.S. Senate, said the success of the candidates for lieutenant governor and secretary of state in Illinois signals "a new trend among American voters.

"They are fed up with Gramm-Rudman, they are fed up with the government's nonaction on AIDS and they are fed up with Congress and the Democratic leadership," said Freeman.

Debra Freeman and her husband, Larry Freeman, who is running for governor, said they believe they will now have to be taken seriously by other Maryland candidates and included in campaign forums and debates. "It's going to be hard for anybody to keep us out," said Larry Freeman.

They said NDPC, which is not affiliated with the Democratic Party, hopes to field about 500 candidates in the 1986 Maryland elections, including candidates for all statewide and legislative offices. Debra Freeman, who ran unsuccessfully for Congress in 1982 and 1984, estimated that NDPC has 1,500 members in the state.
