Lets be clear this is the explicit purpose of the advertising and public relations industry.
1. Create Art (writing, multimedia etc...) intended to influence viewer
2. Distribute Art via Large Scale Channels
3. Hope that people exposed to it take the action you want them to
For Coca-cola they want you to "Buy Coke"
For AirBnB they want you to book a stay
For Politicians they want you to vote for them
Politicians have always used the media channels of the day to advertise themselves. So it's extremely unclear what is news here aside from the fact that Politicians are following Corporate levels of sophistication for advertising.
I think what it really shows is that Advertising in total is a toxic and corrupting business and should be banned outright for all things.
