Gap narrows

Polls showed the US election tightening yesterday as Hillary Clinton campaigned in the crucial state of Florida, grappling with the fallout from the FBI director disclosing more of her emails were under review.

With the US elections now just eight days away, an ABC News/Washington Post poll put the former secretary of state just one point ahead of her bombastic Republican challenger, Donald Trump, at 46-45 percent of likely voters in a four-way race.

In Florida, which is a must-win if Trump is to have any hope of victory, the tycoon overcame a one-point deficit to lead, according to a New York Times Upshot/Siena College Research Institute poll.

The poll gave Trump 46 percent of likely voters compared to Clinton's 42 percent, with former governor Gary Johnson dropping to four percent and Green Party candidate Jill Stein on two percent.

While the 69-year-old former first lady looking to make history as America's first female commander-in-chief is still overwhelmingly expected to win the November 8 ballot, Trump was quick to crow yesterday.

"We are now leading in many polls, and many of these were taken before the criminal investigation announcement on Friday -- great in states!" the 70-year-old real estate tycoon tweeted to his followers.

FBI boss James Comey wrote to lawmakers on Friday, announcing that his agents are reviewing a newly discovered trove of emails, resurrecting an issue that the Clinton campaign thought was behind it.

A previous FBI probe was declared finished in July, after Comey's agency found no evidence that Clinton had broken any laws through her controversial use of a private email server while secretary of state.
