I think the correct measure is vote share, not vote number, since turnout didn't stay constant. We can have a good argument as to whether percentage change in base vote or absolute point change is the right measure. The thing is, by any measure people haven't been deserting the Lib Dems compared to last time, but not all the voters have been living in the right places for their votes to count.

I shan't even get into boundary changes *cough* Oxford West *cough*
