Hmm...Ohio has voted for the winner of every presidential election starting with 1964. That would mean that since 1980, it's voted for Reagan twice, George H. W. Bush once, Clinton twice, George W. Bush twice, and Obama twice. I wouldn't quite call that inelastic, if you ask me.
Then again, I don't exactly know what you mean by "inelastic."
Nate silver coined the political use of the word "elastic" in this article:
http://fivethirtyeight.blogs.nytimes.com/2012/05/21/swing-voters-and-elastic-states/?_r=0Summed up, "inelasticity" means that the state isn't very sensitive to change in the political environment.
This is referring to each election's individual PVI index, not the results of the election.I think "stable" might have been a better word to use than "inelastic", because they have slightly different meanings.
