CHENEY IS USUALLY BEHIND THE BAD IDEAS

First, Cheney is the one who wants to attack Iran:

Bush Admin torn over Israeli strike on Iran, says official

Speaking to The Jerusalem Post, the official explained that within the Bush Administration there is a "hawkish camp" led by Vice President Dick Cheney that wants to employ the military option to prevent Iran from acquiring nuclear weapons, and feels an Israeli raid is the perfect way to get the ball rolling.

On the other side is the "dovish camp" led by Secretary of State Condoleezza Rice and Secretary of Defense Robert Gates that believes the US and its allies must continue with thus far ineffective diplomatic efforts to convince Iran to voluntarily halt its nuclear program.

Second, Cheney is the one who wanted to omit facts about global warming & health:

Vice President Dick Cheney's office pushed for major deletions in congressional testimony on the public health consequences of climate change, fearing the presentation by a leading health official might make it harder to avoid regulating greenhouse gases, a former EPA officials maintains.

...Jason K. Burnett, until last month the senior adviser on climate change to Environmental Protection Agency Administrator Stephen Johnson, says that Cheney's office was deeply involved in getting nearly half of the CDC's original draft testimony removed.

Bush is probably the worst President ever but Cheney is certainly the most dangerous Vice President in history.
