Weak and wobbly

When Theresa May decided to go for an early election, she transformed the nature of her premiership. Up to that point she had been the steady hand on the tiller, righting a ship of state buffeted by the Brexit referendum. By going to the country to win her own mandate, she sought to become more than that. She wanted her own sizeable majority and, in so doing, invited comparison with the two prime ministers who have done the most to shape modern Britain: Margaret Thatcher and Tony Blair. She was asking to be judged against their electoral triumphs.

At the start of this campaign, May looked comfortable in this company. The polls suggested that she would get a higher vote share than either Thatcher or Blair and win a majority to stand any comparison with their landslides. As the campaign has gone on, this has looked less certain. The 20-point Tory leads at the start of the campaign are a distant memory.
