BLOOMFIELD HILLS, Mich. (AP) — It's safe to say that until recently, Republican Paul Ryan had never visited a lemonade stand with a dozen Secret Service agents in tow. And he almost certainly hadn't discussed the tightness of his shirts during a national radio interview. Or been asked to play "word association" by a TV reporter.

It's a whole new world for the Wisconsin congressman.

In ways large and small, life has changed for Ryan in the two weeks since Mitt Romney named him as running mate. Before that, Ryan was an up-and-coming but little-known House member still untested on the national stage.
