ran a very effective campaign which focused on the real issues facing the British people in peacetime – the 1930s had been an era of poverty and mass unemployment, so Labour's manifesto promised full employment, improved housing and the provision of free medical services. These issues were foremost in the minds of the voters and Labour was trusted to resolve them. Churchill's principal theme in the election campaign was always the perils inherent, as he saw them, in socialism, but the Conservatives had to offer an alternative and Churchill stressed to his colleagues that a Conservative government must be constructive. He saw the housing shortage as the main issue and announced his commitment to rebuilding in a broadcast on 13 June but, as with the Gestapo speech on 4 June, he ruined the effect by again insisting that Labour would deploy some form of political police to control the nation. On 3 July, he called for an intensive effort by his Cabinet colleagues to promote housebuilding and prepare legislation for both national insurance and the NHS, but his concerns in these areas were unknown by the electorate to the extent that, when he addressed an audience in the Labour stronghold of Walthamstow that evening, he was almost forced to abandon the event because of booing and heckling. Many commentators felt that Churchill's election speeches lacked "vim" and there is a view that he was much more interested in what was happening in eastern Europe than in the United Kingdom, but eastern Europe was Churchill's primary concern at Potsdam. Polling day was on 5 July and, after the agreed delay for collection of the overseas service votes, the results were declared on 26 July. The outcome was a landslide victory for the Labour Party with a Commons majority of 146 over all other parties. Churchill had a constitutional right to remain in office until defeated by a no confidence vote in the House of Commons. He wanted to exercise this right, partly so he could return to Potsdam as prime minister, but instead was persuaded to resign that evening and was succeeded by Attlee. The caretaker ministry's short term of office means that a critical assessment of its performance is difficult but Stuart Ball credits Churchill as "a good constructor of cabinets" and says that, although the 1945 government is sometimes unfairly dismissed, "it was a sound and capable team".
