The Tories are the natural party of government in this country. In countries that have one party historically dominant over the other, the opposition typically has to work a lot harder to win elections.
Why, as a Swede I do believe I'm familiar with the concept of a historically strong and dominant party. But I also know that the dominance has a tendency to eventually turn into arrogance and that sooner or later it piss off the public. I'm pretty sure the Tories have reached that point and the bottom of the barrel of Tory talent are hardly likely to turn that around. But anything can happen in politics, so as you say maybe maybe.
I'm not sure though how strong of an endorsement it is of your favoured candidate that you believe she is lying to the Conservative membership and will u-turn as soon as it's politically convenient of her to do so, but considering her history it might very well be the correct thing to anticipate.
