Among the items removed from the campaign office of Prince George's County Executive Lawrence Hogan in a Tuesday night burglary was a copy of a $34,000 survey of Maryland voters, said campaign manager Charles Michael Hoback.

Hoback said the survey was performed Feb. 20 for Hogan, who is running for U.S. Senate, by the Houston polling firm of V. Lance Tarrance and Associates.

On Wednesday, police reported that Hogan's Clinton campaign office had been burglarized sometime between 11 p.m. Tuesday and 8:15 a.m. Wednesday. An electric typewriter, a cassette tape recorder, and some campaign papers were reported stolen. Hoback said yesterday that a key to the front door, newspaper clippings about other candidates and notes on the upcoming Republican state convention in May also were taken.

Hoback said the survey recorded the issues and concerns of voters throughout the state along with demographic information. Hoback said the poll was based on a preliminary survy completed in October, a copy of which was not taken, although it was located in a drawer below the stolen copy.

"In the pre-Watergate days, no candidate would have left survey data in the office. It was locked in the briefcase, under the arm every night," said Hoback. "But since then, you just assume nobody would be stupid enough to do that sort of thing."

"I really think, somewhere along the line, it was political," Hoback said later of the incident.
