SPRINGFIELD — Before long, the Cayman Islands might want to consider including Gov. Pat Quinn in its marketing budget based on how much he’s been talking about the Carribbean paradise and notorious tax haven.

Quinn’s campaign Thursday promoted its second online video of the week, again hitting Republican Bruce Rauner for having at least five personal investments in funds that are based in the Caymans.

The new web-only video produced in-house by the Quinn campaign features plenty of surfside footage of waves hitting the beach and Rauner touting his business credentials.

But its real teeth comes from U.S. Sen. Chuck Grassley, R-Iowa, in footage from a March 2010 hearing involving President Barack Obama’s appointment of Jeffrey A. Goldstein as undersecretary for domestic finance at the Treasury Department.

Goldstein got grilled by Grassley, the ranking Republican on the Senate Finance Committee, for his work at a private equity firm that had set up “blocker corporations” in the Cayman Islands to shield U.S. investors from federal taxes. 

“The only real difference I hear between investing in the Cayman Islands and investing in the United States or the only way the Cayman Islands investments are superior is the possibility of avoiding U.S. tax,” Grassley said in the sound bite captured on the Quinn video.

The release is the second online ad of the week touted by the Quinn campaign going after Rauner’s Cayman Islands holdings. On Wednesday, the governor’s campaign promoted a video the featured an Ohio State University business professor outlining the implications of investing in the Cayman Islands.

Quinn spokeswoman Brooke Anderson declined to say if Thursday’s campaign production would find its way onto television. Here’s the video:
