No, it is not an exception, and two of your (weak) examples mention it, and the second is about consumer spending.
The second specifically says this…
“”An inflation gauge tied to consumer spending was up just 0.9 percent in February””
Sounds like they are trumpeting the one, low, Obama-sycophantic inflation rate as I said.
Please quote to me in any of those articles where a second non-core inflation rate was actually documented.
