they are very vulnerable to a ukip mark 2 or a new british national party, the demand remains out there but not the supply. the conservatives may be racist. they may be the nasty party. but they carry a lot of baggage with them. if a well-funded party with a vaguely charismatic leader emerged - and frankly this isn't impossible - it could have a great impact. where previous parties have fallen down have been on issues like a nazi past, on funding being pulled, on a lack of credible candidates, on their policies being stolen by a mainstream party... as we've seen with people like stephen yaxley-lennon and paul golding it's quite possible for in the first case an utterly unknown member of the bnp or, in the second, a former director of publicity and councillor to have an influence far greater than might have been expected. the demand's out there. is the supply?
