Whitman and Fiorina take note: while candidates with big war chests hold a significant advantage over their opponents, the advantage is diffused when most of the money comes from a candidate's own pockets. The traditional advantages of being the top fundraiser in a race, or being an incumbent, don't confer the same level of success to self-financiers. That trend holds true for candidates from all parties. In fact, in the last nine years, only 11 percent of self-financed candidates won their races. Early primary results in 2010 show this trend may be continuing.
