Of the four - I am discounting Diane Abbott and John McDonnell as no-hopers - the one that has so far talked the most sense is Andy Burnham. He at least seems to have some understanding of the Labour Party's roots, and a coherent story to tell about how it managed to lose touch with its natural supporters over recent years. I have also, in the past two days, been impressed by Ed Balls: the new government's divisive new education reforms, a throwback to the mid-1990s mania for grant-maintained status, will surely give him a platform from which to rally support.
Of the Miliblands, there is much less positive to be said from my point of view. To tell the truth, I would not be unhappy with either of them as leader, and David's so-called 'Blairite' credentials - a fatal drawback if genuine - have always been seriously overplayed in my view. But I wonder whether either of them are quite combative enough for the role at a time when the Con-Lib coalition is threatening to carry all before it.
Certainly Harriet Harman made a good stab at puncturing David Cameron's growing self-confidence this week, and I still don't think it is entirely outside the bounds of possibility that she could come into the race. For one, I don't think she would be entirely happy to see Abbott carrying the torch for Labour's wimmin. For another, I think it's very noticeable that some of the key Brownites who were behind her deputy leadership campaign - the likes of Nick Brown and Kevan Jones - have yet to declare for any of the other candidates.
What this is all leading up to is that, to my mind, the field is currently way too narrow. I am hugely disappointed that Yvette Cooper has decided not to stand - if brother can stand against brother, then why not wife against husband? - but I do understand her reasons. No such considerations apply, however, to the other great absentee from the race - Ben Bradshaw.
He was an experienced and successful minister. He was not clearly associated with either Brown or Blair but was regarded as having been loyal to both men. He has an interesting personal backstory that resonates with 21st century Britain. He is good-looking, articulate and good on TV. Perhaps most importantly of all, he has had a life outside the Westminster goldfish bowl and a successful career in the real world. Why is he not standing?
