"Any" means "any". That would include the (admittedly hypothetical) case of Trump clearly winning in by landslide. Again, "any" means "any". The direct implications of that is that the Dems should re-take the White House by any and all means and under any and all circumstances. That is also a direct appeal to sabotage the US democracy which, as flawed as it is, is the only rule of law based option currently available to the people of the USA. Will that result in a civil war? That is rather unlikely, because for a civil war you need to have at least two credible parties which can coordinate attacks and defensive operations on, at least, a regional scale. I don't see that in the USA. But I don't see how local/regional violence (at times severe) and political chaos can be avoided. We already know that the Dems will never accept a Trump victory.
