White House race could hinge on Pennsylvania

White House race could hinge on Pennsylvania

The 2020 presidential race appeared to be coming down to a handful of swing states once again.

Reuters Polling Editor Chris Kahn says the election could be decided in Pennsylvania.

President Donald Trump took the lead over Democratic rival Joe Biden in the vital battleground of Florida and other U.S. swing states on Tuesday, but Biden pinned his White House hopes on Arizona and a so-called "blue wall" of three Rust Belt states that could take days to count their votes.

Biden was eyeing those "blue wall" states of Michigan, Wisconsin and Pennsylvania that sent Trump to the White House in 2016 for possible breakthroughs, although vote counting could stretch for hours or days there.
