Well, of course, Massachusetts Governor Deval Patrick should pick former Congressman Barney Frank to fill the US Senate vacancy that will be created when John Kerry is confirmed as the nation's 68th Secretary of State.
In the absence of the reform that is needed -- a requirement that all senators be elected -- governors are going to pick interim senators. The Massachusetts system is actually better than in most states; when a seat becomes vacant the appointee only serves for three or four months before a new senator is selected in a special election.
The question with regard to the interim senator, then, is whether the state will be represented by a placeholder or someone who can actually make an immediate and significant contribution.
There are several prospects for the Massachusetts seat who would be good senators. Some have even suggested former Massachusetts Governor Mike Dukakis, the 1988 Democratic nominee for president, although Dukakis says he does not want the position.
Frank does want it.
Just days ago having finished serving 32 years as one of the most outspoken and engaged members of the US House of Representatives, he's actively campaigning for appointment to Kerry's seat.
Frank makes the best case for his selection, arguing that his experience as a former chairman of and ranking Democrat on the House Financial Services Committee makes him uniquely qualified to serve during a period when -- because the "Fiscal Cliff" deal has set up huge fights over everything from raising the debt ceiling to sequester cuts -- the focus of the Congress will be on issues on which he's something of an expert.
