With the Supreme Court set to hear arguments in Davis v. FEC on April 22, 2008, candidates who are using some of their own funds to run their campaigns and the opponents of these candidates face uncertainty in the face of a potential Supreme Court opinion coming down some time later this year.  CQ Moneyline helpfully lists Millionaire’s Amendment filings as they roll in and important questions remain:  What happens to money raised above the $2,300 limit if the Court holds the law defective?  Will the opinion speak more broadly to contribution limitation issues?  For opponents of self-funders, it may be difficult to plan campaign budgets based on amounts raised under the increased limits.
