"Crossroads GPS, the political nonprofit founded by Karl Rove in 2010, announced on Oct. 3 that it has raised $75 million in 2014, just as it begins a massive advertising campaign targeting Democratic candidates for Senate. The group said it plans to spend at least $23 million in the final months of the 2014 election.
What is unclear is how Crossroads GPS can reach its spending goals without coming into conflict with the tax laws that provide it with tax-exempt status on the one hand, and anonymity for its big-money donors on the other."
