If there's a Brexit recession, what we will see is the venom of the Brexiters targeted at Theresa May and her government. The harsh problem is we have a tough negotiating position and will have to make compromises which will mean some Brexiters think Theresa May has got a very bad deal, depending on what their own priorities were.
Some liberal Conservative Brexiters and Brexiters in the business community prioritise full access to the single market - if they don't get single market access then they will blame any recession on this.
Brexiters in the City are similar to the above but will prioritise keeping passporting of financial services, if they don't get it they will say it's ripped the heart out of one of the leading parts of our economy and will blame any recession on this.
Some right-wing Conservative Brexiters want to be able to scrap employment, health and safety and consumer protection laws and if we have a recession will say it's because the government has kept the protections in place in UK law.
Anti-immigration Brexiters will blame immigrants for the recession because migration will still be very high and there will be lots of chaos over Calais etc. Given Theresa May's record on net migration in the Home Office this will start a movement to oust her from No.10.
Left wing Brexiters will say its the fault of globalisation and capitalism that Brexit was supposedly a protest against, and will call for government to take advantage of being outside the EU to be more protectionist.
