SCOTT SIMON, HOST:
This is WEEKEND EDITION from NPR News. I'm Scott Simon. Hillary Clinton has chosen Senator Tim Kaine of Virginia to be her vice presidential running mate. Senator Kaine is a moderate from a political swing state who's made the shortlist before. NPR's Ailsa Chang has this profile.
AILSA CHANG, BYLINE: Up until now, the biggest knock against Tim Kaine as a VP pick was that he's just kind of, well, boring. A few weeks ago, NBC's Chuck Todd read out loud to Kaine exactly what people in politics think of him.
