After the 05 election some research was published showing how unfair the electoral system is.
For each Labour MP elected, approximately 35,000 Labour votes were cast. For each Tory, it was approximately 45,000. For each Lib Dem it was something ridiculous like 120,000.
FPTP could be a good system, but the Boundary Commission, who decide the boundaries of each constituency, seem to be unable to make it fair. There should be no such thing as "safe seats" where the people inside a constituency are such that they always vote for a certain party no matter how bad that party is - but most seats are safe seats. There are only 200 or so "marginals".
re Chris Grayling - he has already made a number of gaffes placing his Home Secretary position in doubt. This will be the last straw and I highly doubt he will be in the cabinet if the Conservatives win.
