It's okay, but sorely lacking. Six on a 10 scale.
Thoughts:
The target audience is too broad. I'm seeing female retirees, homosexuals, ESL business owners, young multi-race families, etc. The breadth of the target audience dilutes the messaging.
Having said that, it's an announcement ad. Its purpose is to let people know she's running. Refined targeting may not be important. In fact, it's probably cost-prohibitive at this point. You can bet her people are testing response by demographics, which will inform her ads down the road.
The presentation was good. The music was uplifting and the sound bytes give the viewer the "feel-goods." Plus, the quick cuts (2 to 3 seconds per shot) give the impression that her campaign is engaged, fast-moving and proficient.
The ad isn't designed for people like us, of course. Nor is it designed to pull in folks on the far right or left. The former won't vote for her. The latter are already inclined to do so.
She's (smartly) trying to get the attention of the middle. To that end, her ad is okay.
Last thought: she needs to display more energy. She comes across as unexcited, which may be perceived by some as entitled (i.e. "This is my time to be POTUS.")
Question for you marketers: If you were running Clinton's campaign, how would you design her ads?
