Democrat Kamala Harris made her closing pitch for the U.S. presidency at a historically Black church and to Arab Americans in battleground Michigan on Sunday, while her Republican rival Donald Trump embraced violent rhetoric at a rally in Pennsylvania.

Opinion polls show the pair locked in a tight race, with Vice President Harris, 60, bolstered by strong support among female voters while former President Trump, 78, gains ground with Hispanic voters, especially men.

Voters overall view both candidates unfavorably, according to Reuters/Ipsos polling, but that has not dissuaded them from casting ballots.
