It's actually pretty catchy...
Sure, it's catchy, if songs like Stupid Hoe by Nicki Minaj are your thing.
This is why 70-year-old men need to stop trying to relate to youngs.
I doubt McConnell had anything to do with creating the add.
Of course not, he'd probably notice the fact that they spelled his own name wrong. Overall it was just incredibly sloppily/hastily made, and in general another cringeworthy attempt at relating to young people made by old Republicans.
Irony, ever heard of it?
By talking about 70 year old men trying to relate to young people you missed that this add is likely crafted by people in their late 20s/early 30s and you keep up that misperception by mentioning "old Republicans".
Furthermore this ad is clearly directed to the general public, its not youth related. You need to be a self centered teenager to get that idea.
