Poor man - 200 years later and the conservative, anti-reform rags are still at his heels

Prof Turley and his colleagues at Aberystwyth don't really have any concrete (pardon the pun...) proof for their claims of where precisely in Winchester Keats wrote 'To Autumn' and what countryside may have inspired him there to choose particular images over others. And their claim that Keats's 'To Autumn' is more political than previously accepted because the land Keats may have been admiring in his poem was owned by a profiteer landowner, seems a little tenuous. Doesn't this repeat Andrew Motion's mistake of trying to create a (sensational? sellable?) new angle by "reading in" more politics than is critically sustainable? In my experience such approaches tend to underestimate the transformative power of the poetic imagination. The images that Keats gave us carry far more significance than the actual landscape of the time which may (or may not) have inspired them.
What do others think?
