Because this election cycle is different from all other election cycles that I remember in my lifetime. What you are witnessing is an expression of a resurgent nationalism that is even a bit less nuanced or subdued than that under Reagan in 1981 and likely greater than at anytime since 1945.
“On your feet stand up tall!
Freedom’s on our shoulders, USA!
Enemies of freedom, face the music, come on boys take them down.
President Donald Trump knows how to make America great.
Do from strength or get crushed every time.
Over here, USA!”
UPDATE: Yep, those uniforms have a lot in common with the vintage 1945 uniforms from our “War Bond” drives.
