I've listened to Republicans say over and over again that we should focus on enforcing the laws that we have. The great hypocrisy of that statement is that they are deliberately handcuffing the enforcement agency that oversees current law.

If [lawmakers] lose elections in part because of their votes on the background-check bill or their position on the terror gap bill, then there will be a rethinking of this issue within the Republican conference.

What is happening in Iraq now is awful, but it is a consequence of our invasion, not our withdrawal.

There are all sorts of shades of gray when you're working on economic policy and tax policy and health care policy. There's no gray on this issue, to me. This is a gun lobby that is raging out of control, that doesn't even represent its own members.
