There's an established school of thought that larger turnouts benefit the Democrats, the acceptance of this is evident in GOP actions over the years that are easily interpreted as being primarily designed to suppress voter turnout, particularly in urban areas. Simply by making it harder to vote. There's been plenty of action on that front this cycle, with numerous legal challenges to changes that have made voting easier.
Now what i thinks interesting about that is that Trump's greatest strength has been his ability to engage voters through his behaviour, not just his fans, but indeed those that oppose him.
And here we are, with predictions that this election will see the greatest voter turnout in decades, with over 100 million votes cast pre polling day. Which is a record in it's self. There's no denying voter engagement is incredibly high, and I think it's difficult to argue that isn't nearly all because of Trump
So if it holds true that greater turnout favours the Democrats, and that the Donald is the primary cause of greater turnout, then it follows that his greatest strength will be the cause of his downfall.
Oh the ironing.
