HARRISBURG (AP) – Legal challenges and a mountain of uncounted ballots are promising a long watch to find out who the people of Pennsylvania chose as president. A host of other major races in the state also stayed unresolved. Voters turned out in large numbers for an election that produced few glitches. But the decision to greatly expand mail-in voting means it could be days before it’s clear whether President Donald Trump repeats his Pennsylvania victory from 2016 or whether Joe Biden would collect its 20 electoral votes. Currently, President Trump is ahead of his Democrat challenger in the Keystone State.
