I live in the constituency of Greenwich and Lewisham. The current Assembly Member (AM) for Greenwich and Lewisham is Len Duvall, Labour, a basically decent bloke and good representative. He won the last election by a majority of 14,083, a comfortable margin, and is therefore highly likely to keep his seat.
In safe Labour seats, I think it is worth voting for more radical candidates, in the hope that eventually the Labour party will realise that they cannot keep on playing to the Middle England vote (e.g. cutting income tax while raising the tax burden for the working poor).
In Greenwich and Lewisham, there are two strong non-Labour candidates: Chris Flood (Socialist Alternative) and Susan Luxton (Green). Both are very good local councillors, Sue in Ladywell and Chris in Telegraph Hill. Both are very nice people. Both have good policies. And Sue is a blogger who links to this blog, which gets her lots of points.
What makes Socialist Alternative different from many other left parties in local politics is an absolute dedication to local issues, and making things better on a local level. The votes that their candidates get - Ian Page and Dave Nellist for example - indicate this.
There are in addition a whole bunch of right-wing populist and other minor parties standing here, who I won't bother mentioning. The BNP are not standing, as the far right is represented by Tess Culnane, representing the National Front. Culnane, a supporter of the expelled former BNP leader John Tyndall, is basically too far to the right, too much of an old-fashioned fascist, to fit in with the current Euro-nationalist British National Party, which indicates how far beyond the pale she is.
The Left List, the electoral front for the Socialist Workers Party, are putting up Jennifer Jones. Last week I posted a guest post on some of the many, many reasons not to vote for Jones. I'll just add that it shows how much contempt the SWP show for the people of Lewisham and Greenwich that they're standing a child who has no political experience beyond the petty world of student politics, where, even in that unsavoury swamp, she has excelled herself in fratricidal and bureaucratic thuggery. She seems to have no interest in local issues, and a sole focus on gay and lesbian identity politics, on supporting Islamist 'anti-imperialist' movements, and in a pathological hatred of Israel. It also demonstrates the contempt of the SWP for the socialist movement that they are willing to dent Chris Flood's vote; one would have thought that they'd stand aside when there is a socialist politician with a genuine local base. Well, no, I guess one wouldn't expect that actually. (See this discussion at Socialist Unity on that issue.)
