Rush may be softening his audience to gradually get them ready for the real reason.
We all seem to think conventionally that we can work this out in a couple of years. Meantime, our enemies have decided it is now or never. They fully expected for Hillary to win and that would be the end of this constitutional republic - finis! Now they have turned to their most radical constituents - AOC, etc. - and embraced violence.
Dinesh DiSousa (?) will tell you the Dems always turn to violence: the 'Civil War', the KKK and now Antifa, when the don't get their way. They have set their sights on taking this election by any means possible and they don't intend to peacefully accept defeat.
Rush's slow logical methodological approach might seem wise, but the storm may not allow the necessary time.
