LAS VEGAS — President Donald Trump and Democratic rival Joe Biden went on offense Sunday, with each campaigning in states they are trying to flip during the Nov. 3 election that is just over two weeks away.

Trump began his day in Nevada, making a rare visit to church before a fundraiser and an evening rally in Carson City. Once considered a battleground, Nevada hasn’t swung for a Republican presidential contender since 2004.

Biden, a practicing Catholic, attended mass in Delaware before campaigning in North Carolina, where a Democrat hasn’t won in the White House race since Barack Obama in 2008.

Both candidates are trying to make inroads in states that could help secure a path to victory, but the dynamics of the race are remarkably stable. Biden has a big advantage in national polls, while carrying a smaller edge in battleground surveys.
