If you add the Labour 35.2% plus the Galloway 21.9% (and don't include the Liberals) it totals up to 57% of the vote being Anti-Tory.
It also totals up to 65% being anti the official Labour candidate.
We can all play the game of saying that every vote not in favour of one thing must be 'anti' them, but most people would vote for the candidate that they wish to succeed.
