What does the Rochester & Strood by-election mean for British politics?

UKIP’s victory in the Rochester & Strood by-election gives the party national credibility, writes Paul Whiteley, and their recent increase in membership gives them the ability to effectively target key seats in the constituency campaigns in the general election. Electorally speaking, however, the division on the right is much more significant than the division on the left, even if UKIP is winning discontented working class voters to their cause.
