Has the climate that brought the UK to Brexit grown, changed or dissipated?  May, previous to the refereundum wanted to have the UK remain in the EU.  Post-Cameron, as PM, she has immersed her Party and gov't into doing a Brexit.   Being that May, and for that matter anyone of politicians at this level, are not stupid people, must have polling information that provides a definite support for her route to the divorce from the EU.  This is not something that May would or can fight an election.  That makes this real and going ahead.
