The other week I asked whether the Lib Dems were a party of government or a party of protest. Many welcome comments were made, including a good one pointing out that a political party can be both: that to reach government it needs to be a vehicle of protest, to identify what’s wrong so that it can offer change.
As I thought about that point, I read Ben Marguiles’ blog on Liberal/Lib Dem electoral performance in relation to other parties. Whether Lib Dems like it or not, his observations highlight the contingent relationship between the party and the politics of protest.
Marguiles observes that previous analysis shows that when the party system is polarised – i.e. the two main parties diverge from the centre, the Liberals and their successors have done well. This was the case between 1945 and 2010 when Britain had a two-and-a-half party system. But where the political party system as a whole is polarised, the Lib Dems suffer. Marguiles puts this down to the rise of other political parties, like the Greens, SNP and UKIP, which all drew votes away from both the centre and both Labour and the Tories. The result? The Lib Dems saw their share of the vote drop. Marguiles does add a rider to this; that the party’s in government may also have made it vulnerable, but that may be due to insufficient data analysis having been done on that specific topic.
