the survey by YouGov is more subtle than that chart.Reality is however, what would chart look like when leavers realise only option is "no deal". Will they go to the "no deal" or "remain" segments.???Boris 'vows to IGNORE MPs' efforts to block No Deal'
Boris Johnson could steamroller any attempts by Remain-backing MPs to block a No Deal divorce, his allies claimed today, as a new poll suggested a majority of British voters still back Brexit.mol.im
Statistics can nearly always say what writer wants saying...
If it comes to a 3 way vote: no deal, softer brexit than May's deal or remain, remain will win.
If it's a two way vote: no deal or remain, remain would still win. This is because the middle group of voters (May's deal or softer brexit than May's) would prefer remain to no deal.
*softer brexit: like JC's deal.
