After the Berlin Wall came down I visited that city and I will never forget it. The abandoned checkpoints. The sense of excitement about the future. The knowledge that a great continent was coming together. Healing those wounds of our history is the central story of the European Union.

You don't have to be a brilliant historian to know that in Europe, messing with countries' borders, messing with their self-determination, their ability to choose their own futures, this is extremely dangerous, and that's why I think it is important to stand up to Putin.

I think the country requires fresh leadership. I do not think I can be the captain to take the country to its next destination.

Yes, America must do the right thing, but to provide moral leadership, America must do it in the right way, too.

We're going to need to absorb some pain. The Republicans want to pile all the pain on people who can least afford it and the middle class and Democrats under his leadership want to make sure that we can address deficit reduction and continue to make investments and shared sacrifice is going to be imperative in order to be able to do that.

Leadership is an act of submission to God. To be a leader means listening to all kinds of people and situations. Out of that listening, we are hoping to discern the mind of God as best we can. This is the price of leadership - it's an act of sacrifice. So leadership is part and parcel of the work of submission to God.

Leadership is particularly necessary to ensure ready acceptance of the unfamiliar and that which is contrary to tradition.

Texans deserve better than failed leaders who dole out favors to friends and cronies behind closed doors. It's time for a governor who believes that you don't have to buy a place in Texas' future. It's time for a governor who believes that the future of Texas belongs to all of us.
