WASHINGTON — With Election Day in sight, Donald Trump tried again for the discipline and restraint that has eluded him for months, hoping not to blow a burst of momentum that has him closing on Hillary Clinton. Clinton and her allies, meanwhile, are doing her best to trip up Trump.

The candidates were slated to take their tussle to Florida and North Carolina on Thursday, two lynchpins in Trump’s plan to take the White House. With five days before Election Day, the unconventional Republican candidate was hewing closer to convention, running some upbeat ads, bringing out his wife for a rare campaign appearance and trying, publicly, not to veer off-message.

“‘Stay on point, Donald, stay on point,’” Trump teasingly quoted his staff as saying, as he campaigned Wednesday in Florida. “No sidetracks, Donald. Nice and easy. Nice and easy.’”

Melania Trump was scheduled to campaign in Pennsylvania Thursday, her first turn on the trail since the Republican convention in July. The former model will try to counter the Clinton campaign’s pounding attacks on Trump as anti-woman, a strategy Democrats see as the best hope for rattling the Republican opponent and driving female voters away from him.

Clinton took that message to a massive audience Wednesday night during the final game of the World Series. The Democrats aired a series of attack ads that highlighted Trump’s lewd comments about women. Trump’s advertising was a mix of positive and negative spots, including one promising “a future brighter than our past.”

The Clinton campaign is trying to keep Trump’s history of vulgar and disparaging statements about women, minorities and people with disabilities fresh in voters’ minds as they head to the polls.

Among those conveying that message for Clinton is President Barack Obama, who was due to campaign in Florida on Thursday, as Clinton headed to North Carolina for rallies in Raleigh and Winterville.

Trump can’t win the election without carrying Florida, underscoring how narrow his path to the White House is. Trump campaigned in three Florida cities Wednesday — Miami, Orlando and Pensacola — and will follow up with a stop in Jacksonville on Thursday.

“We don’t want to blow this,” he told rowdy supporters in Miami. “We gotta win. We gotta win big.”

Despite tightening polls, Clinton still has more options, which was underscored by her decision to make a late stop Wednesday in reliably Republican Arizona.

“This state is in play for the first time in years,” Clinton exclaimed during a nighttime rally on the campus of Arizona State University.
