He needs to throw in “communist”, “socialist”, “liars”, and be specific in the indictment of their failure. Maybe a rendition of The Snake would be in order. Fitting and hilarious.
He should talk about how defending the sanctity of America as a nation, is about defending the sanctity of every American’s freedom as an individual person, Then point out that this isn't ‘nationalism’ in the negative connotation brought about by Communist and Fascist nations. This is about protecting a unique nation that has been the beacon of liberty to the world. It's about protection of individual liberty, and protection of our Constitution and the mechanisms whereby our unique nation protects those individual liberties from being trampled upon.
etc.
