I think they're going to squeeze out all sorts of other spending items.

I think it's absolutely essential and inevitable that we are going to reform those programs. How, is another question. There's very little interest, now.

It really depends crucially on how many people you want to compensate. If you include farmers in Iowa [whose grain shipments have been disrupted], then it could expand mightily.

To improve highways, we should rethink the way revenues are raised instead of only increasing them. The present highway finance system can remain viable for some time, but the right reforms might give us a system that not only pays for roads, but also allows us to manage traffic flow and ensure that scarce funds are invested in projects with the greatest public benefit.
