Bloomberg's John Heilemann says that Bernie Sanders is gaining ground in the Empire State.
JOHN HEILEMANN: I do not believe she does, and I do not think the Clinton campaign thinks she does. She will come in here as the frontrunner, without a doubt. She has a strong hold on a lot of constituancies that matter a lot in New York City.
But Sanders will be a very strong candidate upstate, he will play well on Long Island, in both Brooklyn and Queens.
She will be the frontrunner -- and likely so, she's won statewide twice. But that was ten years ago, and Sanders I think will give her a run for her money...
Which is why Hillary Clinton has been here in New York and not in Wisconsin.
