Look how much cash Bernie Sanders has raised so far.

When I saw the headline at Fortune, I had to do some digging and sure enough, the media is relying on polling data, because after all, polls can tell you what you want to hear if you know who to ask.

Other media outlets are glomming onto the the counter-intuitive union endorsement of Hillary Clinton, who hasn't really been fighting for labor as much as Bernie Sanders.

One union leader said he personally loved Bernie but endorsed Hillary because he thought she had a better chance of winning, but the media and the union leadership cannot see the groundswell of support for Bernie coming from the rank-and-file.

It appears the media are presupposing a Clinton advantage based on the assumption that union leaders held a vote among the members. I couldn't find the rules for endorsing candidates, but The Daily Caller reported that Bernie and Hillary met with union leaders in a private meeting. which suggests that the rank-and-file union members don't have much of a voice in the matter.
