It's not easy making a worthwhile point when you go on Meet the Press, because you have to answer questions from Chuck Todd, who never asks you about anything worthwhile. But Speaker Paul Ryan did a pretty good job regardless in his appearance yesterday. Conservatives opposed to Ryan because immigration is their number one issue and they think Ryan is a pro-amnesty sellout will be pleased to know - I think, you never know with them - that Ryan vowed there will be no comprehensive immigration reform taken up by the House as long as Obama is president. Why?
