I will refrain from comment on the final pick.
To be more serious for a moment, the result can be read as a wad of demographic tea leaves at the bottom of Hillary’s teacup: The chosen song was by far the most "soccer mom" of the options, pointedly bypassing the civil-rights-era echoes of the Temptations, the more youth-oriented Smashmouth (purportedly Bill C.’s pick, but in general a weird case of wishful thinking and cool hunting that missed the mark), and the overly politically aware U2.
For many potential Clinton voters – especially working and middle-class women of all ages, single mothers, new immigrants, exurban families, and many more – the Celine choice is going to be a much more sympathetic and welcomed selection than you would think if you went by the media and the blogophere, which predictably went right into mockery mode. As I argue at length in my book, critics and pundits are, by and large, exactly in the place in the culture least disposed to understanding Celine’s appeal, and have always, as they are this week, stood by and jeered while Celine went on to be embraced by hundreds of millions of fans around the world. At least for once Hillary’s managed a genuinely populist move here, rather than backing away into the neutral zone her handlers seem to prefer. Although maybe that’s because she doesn’t make a very convincing populist, which leads to our next problem…
Aaaaargh Celine Dion aaaaarrcgh I’m burning
