Tory or UKIP; haven't yet decided. Before the UKIP surge I thought that their only role would be to force the Tories towards working-class Thatcherite conservatism (which they are doing).
However now it seems they have a real shot in some seats and must be taken more seriously. Given a choice between Tory or UKIP I would vote based on the prospective candidates and their local manifestos.
In any case, the most important thing is to ensure Labour never get their hands anywhere near power again. Red Ed is certainly a great boon to the small-c conservative cause in that regard; he's now more unpopular than Nick Clegg!
