These traditionally red states, Arizona, Utah, Georgia...all showing a tightening of the polls has to be concerning for Trump. In a close state, ground game and organization are essential...if these states still are within a few points as November comes closer, you have to think Clinton has a good shot of picking one or two of them off.
Again, Trump has no concept of red and blue states. He's listed NY, CA & WV among his top target states. Even hired a pollster for NY.
^^This. Sounds like Trump is still stuck in primary mode and is going for the 50 State Strategy. I'm surprised he hasn't said that he's going to win every state (or has he).
