Democrat Senate Majority leader Harry Reid on the Senate floor this morning:
"Instead of joining us on the right side of history, all Republicans can come up with is this: slow down, stop everything, let's start over," Reid said.
"If you think you've heard these same excuses before, you're right. When this country belatedly recognized the wrongs of slavery, there were those who dug in their heels and said slow down, it's too early, let's wait, things aren't bad enough."
As I remember it Abraham Lincoln was a Republican.
