I have a few small comments:
The "guepiere" at the beginning probably references this article of clothing:
http://nl.wikipedia.org/wiki/Gu%C3%AApi%C3%A8re
and I'll bet the whole sentence is a reference to her outfit in the MJ video (pink vinyl clothes and one of these) and that's how the public is perceiving her (presumably "plebiscite" refers to the opinion of the public).
"cours de récré" probably refers to "recreations" (like diversions, etc.) and "Navarre" is probably synecdoche referring to ML's success in Spain.
