That said, if you remove the 1/3 of tories now tactically supporting them (a figure i think will drop) you have them down in the mid-teens in one of their strongest areas without a lib-dem MP. They won't elect anyone on those figures anywhere.
I'm really intrigued by this tory vote; it looks a lot like they are responsible for the LD vote holding up in O&S - but why do you think this group will drop? One of the features of English politics to me is the intensely pragmatic nature of the right - and it looks like the tory voters of Oldham are going LD in substantial numbers despite all the frothing of the more ideologically pure tory press who have made clear their opposition to any idea of coalition candidates. If this kind of tory tactical voting is replicated nationally, there are a lot of LDs who will benefit.
Not saying this will happen, but it appears to be happening in Oldham and I don't see especially why it won't elsewhere.
