those out there. as it moves along there were no restrictions spinning there is good reason for that. in there is some problem with that generation. in what we know those clauses that they're not even big enough to file the tax return but along the mass campaign. those campaign during

$25,000 in it needs to be disclosed. and with advocacy with those organizations there is a lot of distrust when we see an advertisement on television of the generic sounding name i think we tend to discount that but with questions how much we trust especially when uc the third party organizations. >> host: did they have a paid consultant?

>> not to my knowledge. but those who engaged in the practices make different types of coalitions and partnerships. the corporate groups and -- at an art with entirely different strategies that the extreme right and left the other in the middle of the spectrum. >> has that professional bet with the system? in the guess and no. it is a good thing to get more people involved in politics. and also with the competing interests.

so how people have their say before the policy makers. and that can be a very valuable thing. where i do get concerned is the bargaining to get involved in the first place. they end up encouraging people to get involved where people already represented in the process. that the equality that members of congress for those a don't hear from others that all. and the concern with the astroturf campaigns are carried out makes us distrust the process and

then there would help them with the political system. i do think the work that people do is great especially work with advocacy organizations. partly but trying to get the message out to the public. >> host: on location at ucla talking with professor walker about his new book grass roots for higher. the last question, where does the term grass-roots come from? >> a long history in the u.s. and not there for "the new york times" said grassroots is deal to many in politics and have deep roots in the tradition rethink of grass roots is

free with the concerns of business. it is where we develop their say. now has more engagements we see that traditional association and now works with the same consulting firms. it is an important part of this andean something fundamentally different now. >> host: take you for your time. >> today i will talk about

the future. never making predictions isn't knee-jerk but i will quote from that great philosopher. prediction is awfully hard to do especially if it is about the future. [laughter] i am a physicist we can talk about the future of the universe billions of years from now but i will quote from the other philosopher woody allen that he trinity is an awful long time especially for the end. [laughter] so you may say what does a physicist do anyway? three physicists invented dutch transistor to construct the first

computers from the internet. and to reinvent television. the x-ray a regime -- machine and the gps system and we love to make predictions. we predicted that the internet is a forum of high culture and high society. >> but teenage boy is logged onto the internet. and grandpas' and 50 percent of the internet will be pornography. [laughter] so before we begin to the

incredible sensational development with the cautionary story we have a great french revolution he had begged guillotine and a priest and a physicist just like me about to lose their head. he put the priest said on the chopping block than they would ask him do you have any last words before resize your head off? he said yes. god from above shall set me free. all eyes on the blade. the blade came down and stopped right before it hit the neck of the priest than they have never seen this

before they said god has spoken. and the you have last words? maybe the spirit of justice. so then they raise the blade it stops right before it hits the neck of though lawyer. then dancing in the streets of paris people say justice and mercy today. now the physicist and they asked him the you have last words? he said yes. i don't know too much about guide but i do know one

thing. said the rope is stuck on the pulley. [laughter] then the physicist said if you remove that the blade should come down good. [laughter] . .
