FWIW, pointythings I'm in much the same boat.
Area is dyed-in-the-wool Labour, with 60+% of the votes (on a 60% turnout) and the next 20 constituencies around it are also Labour majorities (Lancashire from the Mersey past Manchester).
Labour may feel their heart is in the right place on services, but I don't like their maths, and for all their criticisms of the LibDem/Conservative coalition, they had years in power to have made positive changes before they became the opposition, and I think some poor decisions were made right through that period.
I don't think it's a clear-cut decision as to which may get into government this time round, but with Labour presumably wanting to stand alone {while the SDP could be an ally for any party willing to drop Trident}, I think there will need to be major compromises once again, unless there's a spectacular turn of events.
Both Labour and Conservative parties still have the skeletons of the expenses scandal to live down (as both could have made changes 20-40 years ago, but were too busy on the gravy train, and enjoyed the status quo), and it may be another 20-40 years before they are not dragged up as to why the two biggest parties cannot be trusted very much.
I see few differences between them - still like Punch and Judy - still critical of things from years ago - still unable to co-operate on much (except when it comes to spending on 'defence' - or rather offence as the defence of the realm is secondary to boots on the ground, on someone else's ground, possibly doing some good, but equally likely, taking casualties and making nasty enemies that work in small cells so cannot be easily identified).
