The 100 biggest donors of 2014 gave nearly $174 million to Democrats, compared to more than $140 million to Republicans, according to a POLITICO analysis of reports filed with the Federal Election Commission and Internal Revenue Service….Of course, that edge doesn’t take into account contributions to deep-pocketed non-profit groups that don’t disclose their donors. They heavily favored Republicans, with reports showing conservative secret money non-profits outspending liberal ones $127 million to $33 million. While that’s just a fraction of the overall undisclosed money spent in 2014, it’s indicative of a dramatic imbalance in a type of big money spending that likely would close the gap between Democratic and Republican top donors, if not put Republicans ahead.
