That's not really what I'm saying. Churchill, I think, was an asset for the Tories, but he did cause them a good deal of damage by saying the Labour Party, which had an impeccably patriotic record throughout his premiership, would require a Gestapo in order to enforce their policies. If he had conducted himself in the same statesmanlike manner as he was to do in 1950 and 1951 - then he would have been much more of an positive force. The Tories didn't need new policies, they already had some - many of which we not all that far removed from Labour - but they said virtually nothing about them in the campaign.
Another point is that the Conservative party machine was barely functioning through years of inattention from Churchill and leading figures in the party, as well as the pressures of the war - Labour's was in far better shape. If the election was held in October, as was originally proposed, then the Tories would have some time to get their internal affairs in order.
