Anyone watching Channel 4 news last night and even more so tonight could see their agenda was to vilify the UKIP party at any cost, their main protagonist in this enterprise was the odious Michael Crick. The purpose of news media is to record what is happening, but this clown is hell bent on becoming the news himself.
To answer the OP; No, Nigel Farage does not want to do this, nor does he realistically expect to hold any balance of power, he just has the balls to say clearly what he believes is best for his country, and if you don't like what he says don't vote for him, but I suspect quite a number will.
