I think we are isolating ourselves, and in so isolating ourselves, I think we're minimizing ourselves, I don't think we are taken as seriously today as we were a few years ago.

There may not be much difference between Democrats and Republicans anymore.

When you're in the minority, it doesn't matter what you're agenda is, you're not going to have the degree of freedom that you have as a member of the majority.

Bipartisanship isn't an option anymore; it is a requirement. The American people have divided responsibility for leadership right down the middle.

Literally minutes before the Senate cast its vote, the administration sought to add the words 'in the United States and' after 'appropriate force' in the agreed-upon text. This last-minute change would have given the president broad authority to exercise expansive powers not just overseas-where we all understood he wanted authority to act-but right here in the United States, potentially against American citizens. I could see no justification for Congress to accede to this extraordinary request for additional authority. I refused.

People were concerned about national security, and that precluded us from having the opportunity to break through on the issues that we cared most about - the economy, education and health care.

This president failed so miserably in diplomacy that we are now forced to war.
