I'm not suggesting Hillary just kicked $7 million or so over to Stein to do the recounts, just that there is no way the idea was hers initially. It's obvious to everyone else that the money is coming from Hillary supporters and is intended to undermine the legitimacy of a Trump presidency.
Maybe Stein really is just trying to exploit some folks who still can't accept reality, but if she were really that crafty she probably could have done better in the general.
