Straining an acronym

OK, I'm going to rant just a bit, but I will keep it short. Here it is:

Acronyms are annoying, especially when they try too hard to make a common word. Take this story from the AP:

After addressing a gathering of sheet metal, air, rail and transportation workers for the soon-to-be-merged SMART union, [Hillary] Clinton spoke at a rally at a high school in a largely Hispanic district of North Las Vegas, with the support of the first Hispanic immigrant elected to the Nevada legislature, Assemblyman Ruben Kihuen. [emphases added]

I get the feeling the sheet metal guys were included just so they could make that "clever" acronym. Kind of reminds me of the Pakleds.
