This is Ralph Nader speaking on October 11, 2007. He refers to a statement by Rep. John Olver (D - MA) that Congress won't impeach Bush & Cheney because if they do, Bush & Cheney will bomb Iran, declare martial law, and suspend the '08 elections.
This certainly isn't the first time I have heard this position, but it is the first time I have come across a video regarding the topic.
