Hi The six month expiration was created for the Republican Party presidential primaries 2012 page It s not that sources expire as you said but on that primary page candidates were was broken down into four categories declared candidates currently speculated candidates formerly speculated candidates and declined So once a speculated candidate was no longer being speculated about he or she wasn t deleted they were simply moved to the formerly speculated section Because Senate Congressional and Gubernatorial elections pages make no distinction between currently and formerly speculated candidates it doesn t apply Not in this cycle in the 2014 cycle in the 2012 cycle or 2010 and so on Thanks
