Oh they understand it....it's another "they never thought they'd liose" situation .....so now they are trying their hardest to sell us on a "deal" that doesn't address any of the issues people voted for and still keeps us beholden to Brussels.... They are far from done... so many idiots being scared by the media thinking a second referendum will sort it all out....I think they might be surprised...I can't see many who voted for Brexit changing their minds...and the way the EU has handled this is likely to  bring in some more Brexit votes to leave due to their pettyness and fucked up idiology
