They hate Halliburton because of Cheney's former, pre-Veep relationship with that company. Can't remember if he was on the Board of Directors, or what, but they're utterly convinced that Halliburton has made off with bundles of cash because Cheney is the Veep. They keep whining about the "no-bid" contract. Never mind that NO ONE ELSE does what Halliburton does, and never mind that the previous administration also had a no-bid contract with them. Correct me if I'm wrong.
Cheney was the top dog at Halliburton.
