It's interesting really, the hardcore Second Referendum lot want Remain on the ballot - but in doing so they're opening the door for No Deal to be the other option.
The problem here is that Leave, and leaving, is a definitive change which opens up possibilities of something different. Remain, meanwhile, appears to be - as the vote was - made up of varying shades which range from 'Let's go back to when things were good in 2012', 'Let's get back to normal', 'Lets undo austerity', Let's build socialism etc etc, which are all in conflict with each other - much like the Remain message in 2016.
Simply saying, 'well people will have changed their minds' is true, and yet the campaign itself to convince the 20% odd in the middle could still fail - meaning the People's Vote campaign could ensure No Deal
