I do not think the results of a single, hotly-contested by election in a time of austerity is a particularly good, accurate or reliable barometer as to public opinion regarding a man placing an unasked-for hand on a womans knee.
Were you to use that result to conclude that women do not really object to a bit of strange offering some unsolicited knee groping, you might find yourself rather more familiar with that knee than you might like,,,,
