Thinking about it, you may have some point.
When the election was called (and all the sad twats such as myself, Len and Genie hurried on to the thread), the split was very very even.
It's only widened to such a Labour lead once all of the (plastics is entirely the wrong label so I'll say) 'less entrenched politically' voted (who may not normally visit off topic so much).
Although as someone you'd consider right wing, my perception is that the political threads are usually dominated by those on the left.
