Democrats are understandably obsessed with Darrell Issa — he’s built himself up as a one-man investigative machine aimed straight at the Obama presidency.

But a handful of liberal political operatives in California — including a former Hillary Clinton hand – are taking their anti-Issa passion to a whole new level, launching a nonprofit group, a website and even paid media advertisements aimed at undermining and investigating the rabble-rousing chairman of the House Oversight and Government Reform Committee.

They say they’re leaving no stone unturned in digging into Issa’s personal and business history. This week, the group will reveal more than 100 pages about an investigation into a fire that burned down a building that housed his business in the early 1980s.

The launch of this group — which calls itself The Third Lantern, and is naming the website the Issa Files — is remarkable because it’s wholly focused on the activities of one lawmaker who has no immediate plans to run for higher office. The purpose of this new group is to make public documents more public, make life difficult for Issa and sow seeds of doubt on his investigations.

They plan to run TV advertisements and other paid media in the future, saying they already have a “significant commitment” of cash. A spokesman for Issa, Kurt Bardella, dismissed the effort as a “misguided and distasteful smear campaign against Chairman Issa.”
