1. The ad lumps Clinton with the losing Republican candidates. They all share a dislike of the presumptive Republican nominee. Do they belong to the same club of establishment politicians who are ruining the country?Nice analysis. I know when I watched the ad, I felt pulled toward Trump. I don't know if it was because of those 4 things or something else. An obvious something else — to me, anyway — is: They're all being so cruel to him that: 1. It makes me want to help Trump (I feel protective), 2. I feel like they're trying to hide something from me and trying to scare me away from thinking about something that, understood, would hurt them, and 3. They seem ridiculous and abnormal, not talking like mature politicians at all (they seem like a bunch of schoolkids whose game could be broken by a simple "I'm rubber, you're glue" retort).
2. The ad shows that Trump is disliked by the Republican establishment. But that is his appeal, not his flaw. Trump already “fired” the losers in the video who are attacking him. Do you believe anything you hear from a disgruntled employee who just got fired?
3. When you remind viewers how many big-name politicians Trump has defeated, it makes him seem stronger.
4. Democrats, independents, and even some Republicans will see that Trump is an “enemy of their enemy” and bond to him.
Here's the ad again, for reference:
