• America's political system has evolved over the last 50 years in ways that have enhanced the power of business lobbies.
• Consider what kind of car you get. Buy cars and other products that have the least impact environmentally.

• As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.
• A zebra does not change its spots.

• I pledge to you today that as president, in my first budget, I will introduce the largest increase in special education ever.
