Swing state vs. Battleground state

I think it’s safe to say most pundits use those terms fairly interchangeably, but Nate Silver argues for a much more narrow definition of the former in which a swing state is one in which the outcome of the election could genuinely hinge upon:

Let me remind you about how I use the term “swing state” here at FiveThirtyEight. When I employ the term, I mean a state that could swing the outcome of the election. That is, if the state changed hands, the victor in the Electoral College would change as well.

The most rigorous way to define this is to sort the states in order of the most Democratic to the least Democratic, or most Republican to least Republican. Then count up the number of votes the candidate accumulates as he wins successively more difficult states. The state that provides him with the 270th electoral vote, clinching an Electoral College majority, is the swingiest state — the specific term I use for it is the “tipping point state.”

We then get a cool graphic of where we can see which states are most likely to swing the election:

From this, we can see that the states most likely to affect the outcome (clustered around 270 electoral votes for Obama) are MN, NH, IA, CO, VA, and OH.  As much as I love that NC is being considered a “swing state” for 2012, as with Arizona (the focus of Silver’s post), if Obama wins here, he’s probably already clinched the election.

  1. Presidential elections don’t have to be this way.

    The National Popular Vote bill would guarantee the Presidency to the candidate who receives the most popular votes in all 50 states (and DC).

    Every vote, everywhere, would be politically relevant and equal in presidential elections. No more distorting and divisive red and blue state maps. There would no longer be a handful of ‘battleground’ states where voters and policies are more important than those of the voters in more than 3/4ths of the states that now are just ‘spectators’ and ignored after the primaries.

    When the bill is enacted by states possessing a majority of the electoral votes– enough electoral votes to elect a President (270 of 538), all the electoral votes from the enacting states would be awarded to the presidential candidate who receives the most popular votes in all 50 states and DC.

    The bill uses the power given to each state by the Founding Fathers in the Constitution to change how they award their electoral votes for President. Historically, virtually all of the major changes in the method of electing the President, including ending the requirement that only men who owned substantial property could vote and 48 current state-by-state winner-take-all laws, have come about by state legislative action.

    In Gallup polls since 1944, only about 20% of the public has supported the current system of awarding all of a state’s electoral votes to the presidential candidate who receives the most votes in each separate state (with about 70% opposed and about 10% undecided). Support for a national popular vote is strong among Republicans, Democrats, and Independent voters, as well as every demographic group in virtually every state surveyed in recent polls in closely divided Battleground states: CO – 68%, FL – 78%, IA 75%, MI – 73%, MO – 70%, NH – 69%, NV – 72%, NM– 76%, NC – 74%, OH – 70%, PA – 78%, VA – 74%, and WI – 71%; in Small states (3 to 5 electoral votes): AK – 70%, DC – 76%, DE – 75%, ID – 77%, ME – 77%, MT – 72%, NE 74%, NH – 69%, NV – 72%, NM – 76%, OK – 81%, RI – 74%, SD – 71%, UT – 70%, VT – 75%, WV – 81%, and WY – 69%; in Southern and Border states: AR – 80%,, KY- 80%, MS – 77%, MO – 70%, NC – 74%, OK – 81%, SC – 71%, TN – 83%, VA – 74%, and WV – 81%; and in other states polled: CA – 70%, CT – 74%, MA – 73%, MN – 75%, NY – 79%, OR – 76%, and WA – 77%. Americans believe that the candidate who receives the most votes should win.

    The bill has passed 31 state legislative chambers in 21 states. The bill has been enacted by 9 jurisdictions possessing 132 electoral votes – 49% of the 270 necessary to go into effect.
