I'm sure name recognition counts to some degree but neither was handed anything as far as I can tell regarding their respective accomplishments. I don't know Blaikie personally but have voted for him twice now based on his views, ideas, and commitment to his community. I've known Ben for nearly 15 years and he's as dedicated as he is intelligent - much like his late father.
I wouldn't classify either as "nepo* babies," as both have worked diligently to get where they are in their lives. And FWIW, neither of them are kids. They're both in their late 30s.
* nepotism generally carries a negative connotation
