Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Cnn"

A: The full sentence is

The President's sweeping plan on student loans follows extended, down-to-the-wire negotiations.

"Extended" and "down-to-the-wire" are adjectives that modify "negotiations". The negotiations took a long time, and they nearly reached their time limit.

A: It is (or it was) very common for TV news anchors to switch to the next story by using the word "meanwhile." For instance, let's say they spent five minutes talking about two world leaders having a meeting. They would then say, "Meanwhile, in Chicago..." and start talking about something that happened there. Or "meanwhile, in financial news, the stock market..." etc. It was so common that if you wanted to imitate a news anchor, you would say, "Meanwhile, in Florida..." or wherever.

So, the title of this newsletter is referencing that old phrase that news anchors used to use so much. (It's possible they still use it but I think it's less common now because the style of news has changed.)

Have you heard of Stephen Colbert? He has a comedy show where he acts like a serious news anchor. He does a bit in his show that he calls "Meanwhile," another reference to the old phrase. If you watch (starting at :26), you can see that he says "meanwhile" when switching from story to story:

Basically, he's saying he doesn't blame China for whatever trade issues he may feel might exist between them and the US. As is often the case with what he says, it is very open to interpretation.

You would not use "at" because... well... because while it has many uses (not as many as on), none of them really apply in this situation.

A: It means fair and not biased toward any side.

"In the middle" instead of more politically "left" or politically "right", if you are familiar with those terms.

A: that's just how the sentence is structured. The "But to x.......?" is used when you're expressing disbelief. Example: A vast majority of people enjoy eating sweets. Some include a vast quantity of sugar in their diets everyday. But to only eat sweets as an alternative to real food on a daily basis? That's going a bit too far.
