The only thing that would make it more cinematic is if they put up a giant screen broadcasting his speech inside the arena.
Obama is boring, especially as a rally speaker.
And he’s not POTUS anymore.
One of Trump’s gifts is to be able to characterize someone humorously in terms that people will relate to, ie see themselves.
When Obama gave a speech critical of Trump, Trump said “I tried to watch it but I fell asleep”
I recall Obama having that effect on me.
