This is one of my litmus tests.

It's so easy to see that every ad for Smiley has content 100% focused on how terrible the other person is.

If, on the other hand, you see any ads for Marilyn Strickland (not running for the same office), you see ads that 100% talk about what Strickland has done.

When a politician only attacks others, pretty good guess the attacker has very little to say about their own work.
