, if you looko me at the polls right now, that most americans, two thirds of americans, agree that the climate is changing, that it is qs by human activity -- that it is caused by human activity in the kind of policies that have worked with pollution are probably the things we should do. about two thirds of americans agree. when they are asked to rate how important that question is to them, they do not read it very highly. if you said to me how much would i be willing to spend to make believe it is, the most important issue in the minds of americans, then i think 100 million bucks would be very low. >> would you go to half a million? can you put a cap on it? >> you tend to think about this in the specific way. my experience of political campaigns is the kind of budgeting you're talking about is pretty unrealistic. the way that things happen in politics, and i am no professional. in my limited experience of if you think you can script what is going to happen, your kind of nuts. if you cannot accept that you will be pretty unrealistic. thanks. the obama administration recently announced
