Cambridge voters today will likely defeat proposed a control on pornography, approve a ban on local testing of nerve gas, and support Harvard's sale of housing to faculty members on a preferential basis, a Crimson telephone survey shows.

According to interviews with 215 voters, the proposal to allow lawsuits against the makers and distributors of pornography--the most controversial of the three referendum questions on today's ballot--will likely be defeated by a 2-to-1 margin, 54 percent to 26 percent.

The random survey, which reached registered voters from all areas of the city, also indicated that some 20 percent of voters questioned last Thursday through yesterday had not yet decided whether they favored or opposed the binding referendum.

University Landlord

On a second ballot question, the Crimson poll suggested that area voters may defeat a ban on Harvard Real Estate's continued sales of housing to faculty members and other University affiliates.

About 47 percent of those polled said they would allow Harvard to continue its preferential sales policy, while 36 percent said they would like to see a halt to the longtime University policy.

Seventeen percent of those interviewed said they were uncertain how they would vote on the housing issue. Although non-binding, the referendum calls upon the state to amend the city's rent control laws to prohibit future sales.

On the third referendum question, area voters seem certain to approve a long-debated ban on the local research and testing of nerve gas agents by an overwhelming margin.

Some 64 percent of voters said they would support such a ban, 24 percent said they would oppose it, and 12 percent said they did not know how they would vote on the non-binding proposal when they went to polling places today.

Who's It Gonna Be?

While all but a few Cambridge voters polled were willing to volunteer their opinions on the three referenda, they were more reluctant to say who among the 22 City Council candidates would win their support.

Some 42 percent of voters said they either had not decided or did not want to say who would get their "number one" votes--the strongest possible method of supporting a candidate in Cambridge's proportional voting system.

Those voters who said they were certain of their candidate choices were strongest in their support for several incumbent councilors.

About 10 percent of those questioned said they would cast their number one votes for Mayor Francis H. Duehay '55. Other candidates garnering from 5 to 10 percent of voters polled were Councilors Saundra K. Graham, David E. Sullivan, and Alice K. Wolf.

Asked to indicate whether their candidate choices would align ac- cording to Cambridge's several political camps, some 44 percent of voters said they do not vote slate politics.
