Two things soured me on Politico for good. (both I think were Jake Sherman but I can't be sure) One was their expose on John Boehner when his book came out where they praised him to high heaven talking about how great he was to deal with cause he would throw cocktail parties and tell stories. (never once mentioning anything about his time as Speaker especially controversial stuff) That was a bad look, and exactly why they have their rep. Not super bad mind you, just kind of distasteful. Don't whitewash history just because the guy buys you drinks and tells you stories of banging secretaries and such. A good story would talk about how it was stuff like that which is why he is still revered in Political Circles despite many a bad decision. Politico has never been known for nuance...
The other was when they would not stop asking Biden about Hunter and the laptop. I get it was a story for a hot second, but by the time they started throwing it around only the NY Post was still talking about it. Even the WSJ** and Faux (outside of Tucker) were slow playing it because it was a lawsuit waiting to happen. Sherman ambushed Biden on the way to his flight to ask about it, Biden said "No Comment" and his PC gave a generic statement and Sherman then clickbaited it saying how Biden dodged the question implying he had something to hide. (I forget the wording but it was accusatory in tone) Sherman then said he would reveal the whole story later implying there was more Biden wasn't saying and more to the story. (even though even the Post wasn't pretending there was more) Politico pushed it since he is their writer even I think on MSNBC. The Bidens then released an official statement, the story was all but debunked and Sherman later on that evening, as promised, told the whole story which was that there was no story. He was just trying to get people to sign up for some newsletter at Politico that he was part of.
The problem with Politico isn't their biases or which way they swing. The problem is they only subsist if both sides like them. They are sort of the last of the old style of Access Journalism and they suck at it much like Chuck Todd does or Andrea Mitchell does because we don't live in that world anymore. Just because the GOP is one of the Parties in power doesn't mean you have to pretend the things they do make sense. Just because you obviously didn't want Biden to be the candidate for the Dems doesn't mean you spit on his family to promote a new endeavor. If you want to be Centrist fine there is a need for that but then actually play it down the middle and call a spade a spade. Don't trade on access, use access to trade on the truth.
Kepler's picture explains it even better.
**This lead to that funny scenario during one of the debates where the WSJ Opinions section was talking about how big of a scandal it was and how it would dog Biden and proves he shouldnt be President while the WSJ News section said it was a BS story and there was no there there and even tweeted at their Opinions section to say so. Obviously the Editor in Chief didn't want to get sued...
