Four candidates in the coming Cambridge elections will discuss campaign issues in the Lowell House Junior Common Room at 7:30 o'clock tomorrow night under the sponsorship of the Liberal Union.

Chief among the questions under fire, according to John P. Chandler '48, acting program chairman, will be the Simpson Report which last year found the Cambridge educational system substandard.

The speakers will be William Ackerly and Rembert Stokes, candidates for the City Council; Thomas Mahoney, M.I.T. professor running for the School Board; and Dennis H. Sullivan, also a School Board nominee.
