Be careful what you wish for. After John McCain so quickly clinched the Republican presidential nomination the last time around, the party changed its rules with an eye to extending their primary season, reaping public interest for months like the long Democratic primary season of 2008.

A document that purportedly represents opposition research targeting Mitt Romney from Sen. John McCain's 2008 presidential campaign was posted online by Buzzfeed reporter Andy Kaczynski.
Immediately noticeable is how many of criticisms of Romney by his rivals during the current race for the Republican presidential nomination could just have easily come from McCain's opposition research of four years ago.
