Go to lib.fsu.edu. On the left menu choose "Find a Journal" then enter your journal title "The Journal of Politics" Click on the one that contains your year. I chose JSTOR. Then on that page search for your title or author. You'll find it there.
Another easier way to do this is to use OneSearch. Just put in the information you have "Is Polarization a Myth? By Abramowitz and Saunders 2008 in The Journal of Politics" and the first item that comes up is your article in JSTOR. Clicking the link goes directly to the aricle!
