As usual there'll be a massive anti vote against a party that has been in for too long, this time it'll be enough to put the Tories in, Cameron's sufficiently bland to appeal to middle england and his touch of Scottishness will probably be enough to pick up a couple of seats up there.
I'll be voting by post from Canada, my constituency is Levenshulme in manchester which is an oasis of libdem in a big red sea. I'll vote libdem because I've
always hated labour (I cried in 1997 when they got in - and hey, I even left the country) and I couldn't live with myself for voting conservative, but i'll see what other fringe parties are throwing down too for an impulse vote. One time (1997) I voted for a guy who's official election photograph was him in a balaclava.
My main beef is the way that most people feel utterly disconnected with the democratic process and the way that the system is geared up to totally disregard the choices of the people. it's too early in the week for a big rant against democracy but if you can, volunteer to help with the count on election day, I always used to (I also helped with the postal votes and canvassing to register electors) because the council would give you time off your normal job and also pay you a bit extra. It certainly opened my eyes to the pointless futility and ludicrous expense of the current party political system and depressed me utterly as I counted BNP slip after BNP slip.
