Justin Trudeau, through careful management, has become a Celebrity. In the world of Celebrity, image is everything. It doesn't matter if if the container is empty as long as it looks good. It's actually an advantage if the Celebrity is vacuous. The Celebrity can then be filled with a whole lexicon of pat phrases, buzzwords, and bafflegab. There are legions of people who don't look beyond the image, and are fascinated by the smiles, the style, the clothes, the press coverage, and the bling. Make 'em ''popular,'' and the fans won't notice that there's really not much, if anything, in front of them. Trudeau is a great frontman. The real power is in the backroom. Those people don't want to be seen.
