I was just stunned by Nige's professionalism
Nige is presenting simplistic, one-issue, policies to people who are looking for simple solutions to complex problems. The amateurism is part of his appeal.
OTOH I don't think the plastic garden chairs necessarily had any intended symbolism - I think they are just a symptom of a poorly planned and underfunded campaign - lots of snouts in troughs to be fed before invoices can be signed off.
ATEOTD none of this matters while Farage can count on free promotion from the BBC and the right wing press.
