A: Vote for May's Deal.
Two opportunities:
• Impede the legislation enacting the vote up to end-June thus threatening accidental No Deal.
• enact the vote; new PM to reorient UK goals during transition.
Three opportunities:
• New PM to reorient UK policy/red lines after Art50 extended.
• Much more time to prep for No Deal.
• Something might turn up.
'B' provides a fresh start to get it right. And increases prospect of No Deal. But also increases prospect of Remain.
The opportunities of 'B' are better but also keeps the prospect of Remain in play - a clear risk to Brexiteers.
'B' is an answer for those who said (and still say) "even Remain is better than May's Deal".
'A' could lead to Remain-minus.
'B' could lead to Remain.
We are where we are. The question for Leavers is which is better? The answer may come down to whether you see an opportunity in Remain (and the associated political turbulence).
Time to choose.
