Tories will clearly pivot to "No Deal" under the next fuckwit who takes over, but equally I don't like their chances of getting that through the current Parliament either.
If they can successfully hoover up the Brexit Party vote without losing too much of their existing support, I suspect a new Tory leader would look to call an election sooner rather than later, it just makes too much sense to do it at a time when Labour are trying to sit on the fence of a debate which is increasingly becoming polarised into No Deal v Remain.
Would expect the Tories to win that anti-Tory/Brexit votes distrbuted more widely between other parties rather than just consolidating behind Labour as it did in 2017, so I suspect both parties likely down on share of the vote v 2017 but Labour more down
