Iain Dale is currently linking to this US quiz called How Progressive are you?
Interestingly, Iain retitles it “How Conservative are you?” Maybe this adds something to the debate about whether Tories can in any way live up to the progressiveness (progressivity? progressivitationalism?) espoused by their leader.
In any case, I scored 348 out of 400, which is apparently “extremely progressive.”

265 for me. This cleared up a few things to my mind.

280 – my score – was already very progressive (or something) and to the left of all the American benchmark scores. I suspect they were running out of superlatives (sic!) by the time they got to 348.
