Having had some time to let the passing of Ted Kennedy sink in, speculation inevitably turns to who succeeds him (and when). There hasn't been an open Senate seat in Massachusetts since 1984, so there's a backlog of long-time Representatives with huge bank accounts all trying to crash the door at the same time... and with a mid-term special election meaning no one would have to give up a safe seat to run, expect a lot of people running.
While Massachusetts currently has a system where there is no gubernatorial appointment but rather a mid-term special election (a result of a legislative change passed in 2004 to prevent Mitt Romney from appointing a Republican successor to John Kerry), there is now a push to update the law to a system more like what is done in Texas: a short-term appointment until the special election can be held. This was suggested by Kennedy himself in a letter released a week prior to his death (which met some initial resistance last week), but with Democrats painfully aware that Kennedy's absence leaves Senate Democrats at 59 and at least one vote short on a health care reform cloture vote, momentum is building for a quick post-Labor Day vote that would change the law again to allow for the short-term appointment. Governor Deval Patrick said on MSNBC that he would sign such a bill, and state House Speaker Robert DeLeo has given it his tacit approval.
Roll Call suggests that, if this passes, the short-term appointee is unlikely to be someone who would contest the special election. They point to former Governor (and Presidential candidate) Michael Dukakis as a likely appointee; he has already given assurances that he will not run in the special.
The next question is: what's the timetable on the special election? It doesn't seem like any changes to the law regarding interim appointment will involve changes to the special election timetable. The Hill calculates:
The special election must be held between 145 and 160 days after the vacancy occurs. Since Kennedy died late Tuesday, that puts the window between Jan. 17 and Feb. 1. Holding the race on a Tuesday, a traditional Election Day, would mean Jan. 18, Jan. 25 or Feb. 1.
