Very simply, hilarity encourages people to laugh at the subject being mocked. When a politician is being laughed at he/ she is on defensive. When on defensive that person is forced to explain. When explaining a candidate is losing ground.
Yes,I get that...I *really* do.But do you understand that American voters are *not* in a laughing mood today? The other day Plugs stated that 120 million people have died of the Wuhan Flu.Of course this,and many other things,must be pointed out.But do you do it with a giggle and a smile in your voice...or do you do it with a "and *this* guy wants to have his finger on the button?" tone of voice?
As I mentioned earlier...think of LBJ's ads (don't know if you're old enough to remember...but I am).His ads...his whole campaign...painted Goldwater as a dangerous,psychotic,psychopath and his TV ads would close with an image of a mushroom cloud.This was months after the Cuban Missile Crisis (which I *also* vividly remember).
I'd want a somber tone...sounds like you guys would opt for giggles.
Just sayin'...
