Will American voters in 2012 enable the third president in a row to serve two full terms? "The only other time such a string occurred was at the beginning of the 19th century — between 1801 and 1825 — with Jefferson, Madison and Monroe," noted Robert Schmuhl in the Chicago Tribune, and they were all from the same party (Democratic-Republican Party) and state (Virginia). "What's distinctive in comparison to the early 19th century is voter volatility, now a central feature of our political behavior. 'Change' elections have occurred on the presidential or congressional levels in 1992, 1994, 2000, 2006, 2008 and 2010 — six of the last 10 times. Yet, amid these turbulent currents, two presidents have won re-election and a third has an opportunity to match the Jefferson-Madison-Monroe streak."
