YouGov’s voting intention figures for the Sunday Times tomorrow are CON 42%, LAB 38%, LDEM 12% (!). That is YouGov’s lowest score for the Liberal Democrats since October 2007 (and for the record, October 2007 saw them at 11%, immediately before and after Ming Campbell’s removal as leader).
Of course while we give a lot of attention to polls showing extremes, almost by definition they tend to be the outliers. That said, looking at the broader picture of YouGov’s daily polling the Liberal Democrats are definitely upon a downwards trend. In early July YouGov were putting them around 16-17%, in mid July they were pretty solidly on 15%, in the last week and a half we’ve frequently seen polls putting them at 14%, this is the second to put them below that.
I doubt this poll reflects a sudden drop in Lib Dem support – they’ll probably be back up around their current YouGov average of 14% on Monday – rather it’s a continuation of that downwards trend. Lib Dem ministers still don’t seem too worried about their position in the polls, commonly dismissing it as just what happens to a junior coalition partner until they find their voice, but presumably it will become a cause of concern for some point (not just for the Lib Dems, but presumably also for Conservatives who fear it placing pressure upon the coalition.
