Hillary Clinton is borrowing some lines from Donald Trump in a new appeal to voters

Hillary Clinton appears to be taking a cue from Donald Trump in a new appeal to voters.

"Think how you'll feel if there was something you could have done but didn't on November 9th. If this doesn't work - personally I can't imagine," Clinton said at the end of her campaign rally in Sanford, Florida on Tuesday.

"Throw your mind a little further and when your kids and your grandkids ask you what you did in 2016 when everything was on the line. I hope you'll be able to say you voted for a better, stronger America," she said.

It's a slightly different tone for Clinton, whose poll numbers have taken a hit in recent days amid an ongoing FBI inquiry into her private email server.

Trump similarly waxes apocalyptic in telling his supporters that a Hillary Clinton presidency would be a disaster - offering unfounded claims about a so-called "rigged" election, and falsely declaring that Clinton wants to abolish the Second Amendment.

"This is our last chance to save our country and reclaim it for we the people. This is it," Trump said at a campaign rally in Charlotte, North Carolina, earlier this month.

Trump has borrowed a few lines from Clinton, too.

"You know, I have a son named Baron and I want to tell you, she is a terrible example for my son and for the children in this country," Trump said at a campaign rally in Warren, Michigan, echoing a Clinton campaign ad which makes the same charge against Trump.

A RealClear Politics polling average Tuesday showed how tight the race is in Florida between the two candidates - with Trump scooting past Clinton by less than 1%.
