Further reforms would create a level playing field  A further reform limiting super PACs would have the effect of leveling the playing field for candidates. Candidates with enormous leadership potential but small wallets have failed due to the lack of resources. Under a reformed campaign finance system, it will be more difficult for well-financed candidates to win purely because of the money they have. Incumbent candidates have a unique advantage over challengers in the present system because of their direct connections to important sources of money.  Campaign finance reform will make elections more competitive and thus enhance higher turnover or "fresh blood" in politics. This is essential for challenging old orthodoxies and bringing in new ideas. It will also make it easier for members of ethnic minorities and the working class to seek office - such groups are disproportionately deterred from candidacy by the current need to raise large sums of money.  Quantitative analysis of elections involving incumbents from twenty-five states across three election cycles indicate that more stringent campaign finance laws increase the likelihood of new challengers to the current incumbent. [1] Financing laws limiting fundraising increase the likelihood of minority-party and independent challengers and produce higher rate of election competition. As a result challengers feel they have better chances against the incumbents.
