1)How is she a regional candidate when she has won in Massachusetts, Iowa and Nevada?
2)That's the same kind of BS the Clinton campaign was saying about Obama in 2008 about how he can't win the big states (New York, California, Florida, Ohio, Pennsylvania). This is just campaign talk to rationalize the fact that you're still running despite the fact that there is no plausible path to the nomination.
I do see a lot of shades of Hillary 08 in Sanders 16. I'm just glad I'm on the winning side this time.
I'm just waiting for the Sanders campaign to start saying "why can't she close the deal?".
