I am sitting here, as a person with a brain, and trying to work through how to check this. I initially thought perhaps I would request the help of others on the internet. Because you know, it's this amazing tool. People like you have been so helpful.
I thought of some other political stories from the past to look up... and now I see that apparently one can't explore things in depth from the past sometimes (although the link to do still shows up). I don't know what the algorithm is. I have used Google news a long time, and I honestly don't ever remember having trouble doing that before. Plus, if there aren't articles, one would think the link wouldn't come up.
I typed in: Biden won't run for president. The fifth link down is a CNN article, Oct 21, 2015 - you can click on Explore in depth (5,457 more articles) and you get lots of articles. But I also searched for Jindal quits race, first link is from Nov 17, 2015. If you click on Explore in depth (946 more articles), nothing comes up.
As a side note, I tried the Jindal article first, and I couldn't find any in depth. So I tried to private message the previous posters to let them know I had figured it out and would be deleting this thread. Since I actually do want to have a real discussion. But I don't have enough posts yet to private message. Ironic isn't it? I guess if I left really helpful feedback like you guys on all the posts I would have enough by now. Geez, why haven't I been doing that?
Now that I see it does work for some stories, I am curious why. It's interesting. This is a media question. That's why I posted it here.
