Last year there were times when Bernie was saying he wanted Lewis to win it, so I think he just wants to get on the sympathy bandwagon for the almost guy.
What I find funny is how he is now sucking up to Ferrari after that falling out they had, and his attempts to split the teams by going public with the news ferrari gets more money.
It backfired, he seemed to think no one else knew when they did, Ferrari were always open about it at meetings anyway. And the teams ended up getting closer and sensing they had Bernie up against the ropes.
