"Sen. Rubio drowning in 'water-gate'"
Yes, that headline actually exists. And, yes, it is from CNN.
The use of "gate" as a suffix is one of my many pet peeves. The Watergate Scandal was not, of course, about H2O. Wondering how it got to be as ubiquitous as it has become, I consulted my trusted friend The Oxford English Dictionary. The first recorded example of the use of "gate" as such a suffix is from National Lampoon in August 1972:
‘There have been persistent rumors in Russia of a vast scandal.‥
Implicated in “the Volgagate” are a group of liberal officials.’
In case you didn't know, National Lampoon was a humor magazine. The use of a "suffix" to name a scandal was a joke. It is now a media staple.
I continue to wait for a Watergategate scandal to happen someday, so that the suffix can self-destruct in its own contradictions and inanity.
