There is an ugly side to Donald Trump that we all have to stop and think about what's going on here.

A lot of people think that regulations bring higher costs, but regulation is also about making sure that someone doesn't get to beat out the competition because they're dumping filth in the river or spewing poisons in the air.

The Republicans underestimated and underestimated and underestimated Donald Trump. And look where that got them. They kept saying, no, no, no, that's not going to happen, we don't have to worry about that.

The banks lobbied Washington so they could write the rules that got us into this crisis. They then lobbied Washington to get the money to bail them out. And then they are lobbying Washington to write the rules so they can get us into the next crisis. It's perfect circularity.

Say good-bye to the Affordable Care Act. That means 20 million people who lose their health insurance, just like that.

My advice is to treat [credit cards] like what they are: little plastic grenades that must be handled very carefully.

If there's any lesson I've learned in the last five years, it's don't be so sure about what lies ahead. There are amazing doors that could open.
