Oh, it goes on…
#US parties regularly had defections and replacements every 40 years or so going right up to when the bipartisan #Boomer alliance began passing laws to prevent that (1990s). Nancy Pelosi and Newt Gingrich were instrumental in that effort. 
Today, the kind of reforms you're suggesting (non-party elections) have been tried in a few states (Louisiana legislature, Ohio state supreme court, etc.) and led to more members of a single party rather than diverse membership, since there was no way to strategically reject unpopular candidates. Now the #Boomers are trying to push parliamentary systems as a way to let party bosses choose the winners instead. 
Proportional representation may look good in #CGPGrey 's YouTube video, but he's just bloviating against Britain's recent reforms to switch to a more-like-the-U.S.A. system. Maybe consider pushing along a different angle. Can you think of a workable alternative? 
#CGPGrey from 11 years ago. A lot has happened in 11 years...a lot has not. How are you doing?

This news about the final pennies 🪙 to be minted reminded me of the now 14-year-old #CGPGrey video advocating for this very day to come.
The U.S. Mint has ended production of the penny, a change made to save money and in recognition of the growing irrelevance of the 1-cent coin. The last pennies were struck Wednesday at the mint in Philadelphia, where the country’s smallest denomination coins have been produced since 1793, a year after Congress passed the Coinage Act. President Donald Trump ordered the penny's demise as costs climbed to nearly 4 cents per penny and the 1-cent valuation became somewhat obsolete. Billions of pennies remain in circulation, but they are rarely essential for financial transactions in the 21st century economy.
It is. First Past The Post lost the argument well over half a century before I was even born. The structural flaws of FPTP were such a mainstream idea that they had even reached the books I read in the school library.
Even for the it-only-exists-if-it-is-on-a-video generation, #CGPGrey's videos about #SingleTransferableVote are over a decade old at this point, and those are comparatively recent.

The Making of Fox News:
"""
It's not enough that conservatives like us, it's important that liberals hate us.

Excellent documentary by Fern & Hoog. Divisive politics is by design. Not surprising but quite something to see it laid bare.
Reminds me of CGPGrey about how "thought germs" in ad/algo-feeds evolve to maximise anger, divisiveness, and departure from truth.
