I am puzzled at how Trump can be winning Ohio by 3, but losing nationally by 6, as reported in this poll.

Easy to explain; look at the top 4 states which hold one third of the US population:
1. California is 12% of the national population and RCP shows Clinton leading by 22%.
2. Texas is 8.5% and Trump only leads there by 8.5% in the RCP poll average.
3. Florida is 6.3% and Clinton leads in the RCP average of polls by 2.7%
4. New York is 6.1% and Clinton leads by 19%.
5. Those 4 states are why Trump lags in most of the national polls; Trump will win two of them if he becomes President but the CA and NY margins far outstrip FL and TX. Victory is in the battleground states, not in expanding his margin of victory in TX or FL(which he must win to have a chance).

Precisely why Clinton made the statement a long time ago to worry only about the electoral vote. She MAY be right, should she live long enough.
