If you have (okay I didn't read the whole article) say 500 Kos bloggers and Hillary only was favored by, say, 110, and after this convention she now has support from 120, the headline would technically be true but the following story would have to be a variety of journalistic jujitsu to take the most minimal of supporting facts and turn that into a justification of the headline.
