If the midterms go badly, Trump may not want to deal with it anymore.
Why would the midterms go badly? Trump and his followers are strongly pushing, and in some cases implementing, the policies that got him elected. By the midterms there will be a mini trade war, various status of immigrants either blocked from entry or on the way out (including a strong Southern border with some foreign casualties), Trump/Russia collusion "proven" to be a hoax and tax cuts still showing good results.
In the meantime the Democrats are just anti the above.
The only possible way out is the economy crashes. What a thing to have to hope for.
