Ohio has many EVs and Obama winning it was a nice touch to make sure he had way more than 270 EV in 2012.
But currently OH is swinging against the Dems. And that is bad.
Traditionally OH was a Republican state, and it has on occasion voted Democratic.
When I look at these EC maps I have to wonder what it will take for the Democratic party to find a way to connect to the 21st century. Since the trend is for “independents” and not party affiliation, I think the need for a magnetic personality (which Obama has, and Hillary does not) is crucial.
