How far will the Lib Dems go ?

This car has been parked in the teachers car park for the last few days and my local school ( to be a ballot station tomorrow ).

There has been an outbreak of ridiculously size election posters in Woking - mostly Lib Dem ones - but there are Conservative ones also. (Haven't seen a Labour poster this election - they must be too ashamed to show their faces.)

But this using a private car in a school for campaigning just seems wrong to me. Schools should just be left alone (none of that intimidating campaigning outside school gates either - by any party.) Why are the Lib Dem supporters so desperate ? But more importantly how do they see out the back of their cars ?

Remember its a school car park, and they'll need to reverse to get out.
