Declarations of war should require some kind of super-majority in Congress. At the least, the nation’s leaders should appreciate the need for deep public support for any sort of drastic action. Deep divisions combined with the new dangers to national security that will result from the war are an especially bad mixture, from the standpoint of preserving basic rights. In their wisdom, the Founders gave us a Constitution that stipulates that Congress must vote to declare war.
Congress did vote on this issue, as Daschle affirmed again just the other day in an interview. The record of the vote was 296-133 in the House, and 77-23 in the Senate. A super-majority is defined, at least when I got my political science degree, as 2/3 of the chamber. I will let you go ahead and do the math, since Max apparently can’t.
