That said, it's probably the only electoral feedback we'll have on national politics until the AV referendum in May. So here are some predictions.
- Labour will win.
- The Lib Dems will be a long way behind - basically, for probably the first time ever, we'll see an anti Lib-Dem protest vote.
- The Tory vote will actually hold up reasonably well, but...
- ...there will be a strong UKIP showing, maybe 10% of the votes or so, which will mainly damage the Tories.
More on this in a week's time.
