For those of us having that "proofreader's eye" (it's not a talent, it's a curse), that kind of stuff jumps out at us all the time.
"Neveda," taken in context with all the other errors that occur on TV, radio, the newspapers, and advertising, is so minor a misspelling that it is not really worth making political hay about.
And yes, formal publications often have proofreaders and editors to check the first proofread version. Still, stuff like that gets through somehow.
Where I worked, they would often distribute official publications to a number of individuals (like ten) for review and comment. One erorr that I caught referred to "megawatts of energy."
Nope.
Had a go-round on that one.
In sum: Meh.
