I love the way President Trump points out how Joe looks different, seems different, moving slowly, etc. The power of suggestion is great - now everyone will have this on their mind whenever they see ol’ Joe. They’ll notice he has aged, fumbles some words, etc. The president is brilliant.
That is a very good point.
A democrat tactic has always been to define, or redefine, republicans in the eye of the public.
And most republicans didn't defend themselves or did so very weakly and meekly.
Remember them labeling President Bush as "Chimpy McBush Hitler"?
But president Trump not only defends himself - he often gets the jump on the democrats and labels them and defines them in the public eye.
That reverses the dynamics - democrats are accustomed to being on the attack - setting others up for ridicule.
With president Trump as their opponent they have to cope with someone who uses their own tactics against them!
And President Trump does it very well!
