marco rubbio had a speech today, this week which is i thought was a quite impressive speech, much more using the power of government to address poverty problems whether it's wage subsidies, whether it's through direct grants, much for a party that has become instinctively anti-government, we beginning to see paul ryan and marco rubbio and some others wanting to affirmatively use government i think in targeted but limited and affirmative ways to address practical problems. >> woodruff: we don't have time to talk about that, unless you can do it in one word, two words. >> david is not completely right. >> woodruff: okay. promise to let you finish that thought later, mark shields, david brooks, thank you both. >> woodruff: finally tonight, author kate dicamillo today became the newest "national ambassador for young people's literature", a post created by the library of congress in 2008 to promote literature for children. jeffrey brown talked with her earlier this week. >> brown: kate dicamillo says she was the shyest child in the world, the kind of kid who wouldn't say boo to a goose. wel
