This is a very promising map for Rubio, if it holds up with new polls being added in the next feek weeks.
There will be some interesting polls over the next couple of weeks. Quinnipiac usually polls Colorado, Iowa, and Virginia together -- and it is about time this week. Within a couple weeks they will poll Florida, Ohio, and Pennsylvania. Hillary Clinton's approvals have been down -- way down -- during the derogatory coverage of the server 'scandal' and the Benghazi tragedy. Hillary Clinton acquitted herself very well. I expect her binary match-ups to look better for her, including against Rubio.
There was a poll of Ohio, and in it Hillary Clinton gained on everyone except Marco Rubio. She was not polled against Rubio. Sure, the poll is by Zogby (who gets little respect). But suspect non-partisan pollsters sometimes get their act together. Give her Ohio, and things don't look so great for Rubio.
