I call baloney. What percentage of the US Congress and governors, say, are people whose parents were in Congress and/or governors? I have no hard data, but my gut feel is less than 25%. That's basically not hereditary.

Anyone with hard data, step right up...

I get that it's a single case, but Darlene Graham did just take Lindsey Graham's spot, like, yesterday.

not literally parent-child hereditary but I mean the political class decides who succeeds itself
