The fact that he hasn't tweeted about every possible statistic is irrelevant to your ask about "the point" of the referenced tweet.

Aahh still going over your head. The whole point I am trying to make is that anybody who is fully objective and data driven would refrain from making such statements online, especially when it is uncalled for. Nate has been consistently taking a pro-establishment stance even when he was proven wrong over and over again. To say it in another way he could have said: Justice Democrats, founded in 2017, went from having zero members in the House to 7 within a year. Including AOC, one of the most popular politicians in the US.

It's not going over my head. You support Justice Democrats.
