Although Every says the idea of the Democrats gaining enough seats in the House and the Senate to impeach Donald Trump is a "fantasy," he does think they could "start to slow down his domestic agenda on almost every single front".
However, this doesn't mean that Trump's trade war with China would cease, as Every explains, it is the one thing he could continue with, whatever happens in the midterms.
"The one thing Trump can do, without the approval of Congress is put tariffs on China ... So therefore if he's not controlling Congress and he can't push for tax cuts and he can't get anything else done that he wants - what's the one thing he can still do? Trade war".
