Parties inexorably tied to a single policy area don’t come along often - particularly ones that gain a handful of seats in the span of 12 months. Over the past two months we’ve seen over 500,000 mentions of immigration. One-fifth of those came from UKIP alone, vastly outstripping all other parties.
UKIP is irresistible social media fodder. It has got a high number of older, less tech-savvy candidates who are prone to Twitter slip-ups. Its leader has a penchant for pulling strange faces and holding pints. You’ll frequently see Farage topping the tweet leaderboards, even though people don’t have many nice things to say.
