More disturbing news about nonprofits, which aren't supposed to be overtly political. Nonprofits are are substantially involved in the fall campaign, and Stephanie Strom and Michael Luo of the NYT report that nobody is likely to do anything about it. It's unclear whether the activity is outside the law. What's certain is that the Internal Revenue Service will do little about it.

The rule of thumb, in fact, is that more than 50 percent of a 501(c)(4)’s activities cannot be political. But that has not stopped Crossroads and a raft of other nonprofit advocacy groups like it — mostly on the Republican side, so far — from becoming some of the biggest players in this year’s midterm elections, in part because of the anonymity they afford donors, prompting outcries from campaign finance watchdogs.

The chances, however, that the flotilla of groups will draw much legal scrutiny for their campaign activities seem slim, because the organizations, which have been growing in popularity as conduits for large, unrestricted donations among both Republicans and Democrats since the 2006 election, fall into something of a regulatory netherworld.

Neither the Internal Revenue Service, which has jurisdiction over nonprofits, nor the Federal Election Commission, which regulates the financing of federal races, appears likely to examine them closely, according to campaign finance watchdogs, lawyers who specialize in the field and current and former federal officials.
