David Walker: “A hundred years ago the Federal Government was 2 percent of GDP. Now it's 23 percent.”

I think we can get there without going to a parliamentary system, but I do think that we need political reforms as well as policy reforms.

Believe it or not, I am 65 years old. Congress has passed timely budget and appropriation bills four times in 65 years. That is an F minus.

The president has got the high ground because he's basically saying, let's go for a long-term deal. I will put Medicare, Medicaid, Social Security on the table. All you need to do is to put tax expenditures on the table.

Anybody who signs a pledge on the right that says, I will never raise taxes, they're part of the problem. They're not part of the solution.
