In its last week of existence, the current city council this morning is debating a proposal by outgoing at-large City Councilor Sam Yoon to limit Boston mayors to two terms. The council will vote on the measure - which would require approval by the mayor and the state legislature - on Wednesday.

Yoon said there were several reasons to limit terms. "It ensures we will have at least once every eight years, new ideas, fresh faces, new people in the office of mayor." He pointed to what he said was an outstanding field of candidates for at-large council seats this year as proof such people exist.
