The Democratic Town Caucus was postponed due to the weekend snowstorm. It is now scheduled to be held at 10 a.m. Saturday, Feb. 23, in the Fourth of July Committee headquarters, 142 Middlesex Ave. The purpose of the caucus is to elect delegates and alternates to the Massachusetts Democratic Party’s 2013 Platform Convention. An equal number of men and women will be elected. All registered Democrats in Wilmington are eligible to participate. “At our 2013 convention, the delegates selected by Wilmington Democrats will debate and adopt our platform for the next four years, catch up and network with other organizers around the Commonwealth, and hear from some exciting future leaders of our party,” said Massachusetts Democratic Party chairman John Walsh. The convention will be held June 1 in Lowell.
