WaPo:

President Obama’s once-broad ambitions to clamp down on the influence of special interests have been largely abandoned since his reelection, dismaying longtime allies in the campaign-finance reform movement….

Reformers of both parties describe the president’s campaign finance record in unsparing terms.

“It’s disgraceful, absolutely disgraceful,” said Sen. John McCain (R-Ariz.), who ran against Obama in 2008 and has spent years trying to limit the amount of money that pours into federal political campaigns.

In a joint letter to Obama on Monday, seven reform groups expressed their “deep concern about the nation’s corrupt campaign finance system and about your failure, to date, as president to provide meaningful leadership or take effective action to solve this fundamental problem facing our democracy.”
