The Conservative party would be obliterated if TM revokes
Within the membership perhaps but to win a GE, middle england has to be won over and plenty of these voters will never vote Tory again once we leave the EU, deal or no-deal.
Also, even a slight downturn in the economy will be blamed (by many) on Brexit and the voters have very short memories.
A revoke would go down very well with business, the economy would be boosted, as certainty is restored and a snap GE could well see the Tories back in power.
The losers in all of this are Labour due to their prevarication.
