Biden closely tends his Pennsylvania roots in election year

FILE - President Joe Biden greets people after speaking about his infrastructure plan and his domestic agenda during a visit to the Electric City Trolley Museum in Scranton, Pa., Oct. 20, 2021. Pennsylvania has been a core part of Biden's political identity for years. It's where he grew up, and he was jokingly called the state's “third senator” even though he represented neighboring Delaware. Now he's returning to Pennsylvania repeatedly to help Democratic candidates even though he's largely absent from the campaign trail in other key battlegrounds like Georgia, Nevada and Ohio.
