Yeah it’s not the best metric. Imagine it the other way around and you’re a progressive who came from a crazy religious Conservative family. Should whether they support you impact people’s votes?
There’s fundamentally 2 reasons why your family wouldn’t support you for President:
- Because they suck
- Because you suck
It’s not complicated to work out which of these applies to your hypothetical person and which of these applies to RFK, but it would undermine his run to say either out loud.
