Letter in The Guardian...
Like Martin Kettle, I remember the "unelectable" Tories winning the 1970 election. It's hard to forget watching a man having to paint extra segments on the BBC's swingometer because the experts had got it so wrong.
Of course, for the Tories to win they will also have to beat off the Lib Dems in the South and the South East. The danger for the Lib Dems though is that at some stage someone is going to raise the issue of their euro-fanaticism, which they have so far managed to hide away in a corner.... but which is a deeply, deeply unpopular part of their programme to the overwhelming majority of those very same Tory/Lib Dem swing voters.
