Allentown, Pennsylvania | Kamala Harris and Donald Trump made their final pitches to voters in the same parts of must-win Pennsylvania on Monday, (Tuesday AEDT) at the end of a tense and eventful campaign that most pundits say is too close to call.

Polls and betting markets have the rivals headed for a tie, although Ms Harris, who out-raised Trump nearly five to one at different points during her campaign, appeared to have regained some late momentum as she blitzed most of the seven so-called battleground states that will decide the election.
