Imagine believing that
A. The NYT's reporting on Biden's age has been particularly tough
B. The degree of toughness is because AG Sulzberger has a vendetta against Biden
I'm sure there's some grain of truth to this story, but it's much more "Biden won't sit down for an interview with us? Weird -- that sounds like he can't. Let's take a second look at the aging stuff." than "Biden won't sit down for an interview with us? We need to punish him. Let's take a second look at the aging stuff."
Also, all the journalists/Biden staffers are dramatically overestimating the importance of this. The NYT's coverage has not significantly impacted Biden's odds in the general election, because few people will actually end up voting on the issue of Biden's age, and those who do will probably have not have had their perceptions substantially altered by the NYT, especially given that only ~10 millionish people read the NYT in the first place, most of whom are already partisan liberals.
Says a guy who takes as the gospel of truth the garbage he hears everyday on Fox and Newsmax.
He's saying it to the guy who still believes Russiagate is a legit story.
