Today's ComRes poll showing a small plurality of voters actually trusting Brown and Darling more than Cameron and Osborne on the matter of steering the economy through the current downturn perhaps can be attributed to the degree to which economic problems of recent weeks really have been mostly international - and obviously so.
The danger is that this becomes an all purpose Labour excuse for all of Britain's economic difficulties, and hammers home the need for Conservatives to highlight that Britain's economic problems have been building for many years, and owe so much to the current government. Some of the biggest events of recent weeks can rightly be attributed to international events. But structural and much longer-term problems with Britain's economy are rightly attributed to Gordon Brown.
