Voters head to the polls Tuesday in three state primaries. Overshadowing Arizona’s, though, is the death of Sen. John McCain three days ago. Also, in Pennsylvania, a state narrowly won by President Trump in 2016, Democratic incumbent Sen. Bob Casey is well ahead of Republican Rep. Lou Barletta, an immigration hawk trying to repeat the president’s success. And host Peter O’Dowd speaks with Regina Clewlow, CEO of the transportation research firm Populus, about the serious uptick in dockless electric scooters in cities across the country, and how she believes they’re the way of the future. That and more, in hour two of Here & Now’s Aug. 28, 2018 full broadcast.
