Ohio chose the president in 2000 and 2004. The independent voters, the so-called swing voters, are the ones who make the difference.
As the country's third-largest state by population, Florida is the crown jewel in the Electoral College among swing states.
I hear you're losing Ohio, but we're doing fine in Pennsylvania.
On election night in 1960 the vice presidential candidate phoned his running mate to discuss the returns:
North Carolina used to be reliably red. Now it's a battleground state.
Florida has been, and will continue to be, a swing state.
Many people think that Puerto Rico would be a Democratic state just by virtue of the inclination of the Latino population in the United States, but the reality is that I see Puerto Rico as a battleground state.
There is no reason why the right Democratic nominee can't win Ohio. President Obama did it twice in 2008 and 2012.
North Carolina was never a battleground state until recently. Now it is, and it's because of migration from the Northeast.
New Mexico has been, in the past, a swing state.
