Jimmy Kimmel: "The US should adopt a primary system"

I strongly agree.
To resolve the polarization of extreme partisan politics,
it is correct that a public primary system would be the solution.
From the perspective of an outsider as a British person,
saying that America's greatest invention is the US Constitution
seems to be a very accurate assessment.
As someone who loves America, it is also quite moving.
He is a stand-up comedian, but he seems very brilliant.
