Too soon to say perhaps. UKIP do not have any MPs remember. If the candidates we have seen so far are in any way representative of the candidates they would field next May then how are they going to hold their own in the spotlight of a general election? Neil Hamilton could not even get elected in a council seat let alone get back into Westminster.
Farage just might get a seat, as he had such a high profile - but he would have to pick his seat very carefully (Rotherham? you cynics, what DO you mean?) and even then I suspect he does put up an awful lot of backs and voters would turn out, to prevent him becoming their local MP. I think the UK press find him entertaining but do they really want UK out of Europe?
Immigration is an issue in some parts of the country, but there are great swathes of the UK where it is not. London, our most multi-ethnic city did not, I understand, vote for UKIP in a significant way for instance. Manchester, our second city (surely?) remains solidly Labour. Milton Keynes, which continues to absorb many immigrants from all over the world, will be Labour controlled for the first time in many years. I don't think UKIP has much appeal in Wales, which has received a lot of EU funding over the years.
At some stage the Libdems will reinvent themselves but it will take some time for many supporters to forgive them...
This morning it is also clear that the local elections were a massive poke in the eye for the coalition parties. Labour, despite keeping a fairly low profile, has done pretty well and the coalition between them lost over 400 seats.
