Massachusetts state lawmakers are poised to send a bill to Gov. Deval Patrick’s (D) desk Wednesday that would allow him to make an interim appointment to fill the late Sen. Edward Kennedy’s (D-Mass.) seat.The state Senate voted Tuesday to pass the bill, which allows for a temporary replacement to serve until the Jan. 16 special election that will determine who will serve out the rest of Kennedy’s term.The bill is expected to pass a routine enactment vote on Wednesday, and Patrick could pick a Democratic appointee by the end of the week. Bay State officials have been mum on a possible interim successor for Kennedy, although former Gov. Michael Dukakis (D) and former Democratic National Committee Chairman Paul Kirk are most often mentioned as possible appointees.
