It’s a race against the clock now for Hillary Clinton and Donald trump to get every last supporter to vote.
Among the 13 battleground states that will decide the election Tuesday, Clinton leads in Pennsylvania, Wisconsin, Michigan and Virginia.
But other states vital to victory are now “neck-and-neck.”
They include Florida, North Carolina and Colorado. And Trump has a lead in Ohio.
CBS News’ Nancy Cordes reports on the Clinton campaign.
“Do we want a president who doesn’t know when to shut up,” billionaire Mark Cuban said at a campaign event Friday.
It was two against one in Pittsburgh today with Clinton and Mark Cuban both pelting Trump’s lack of filter.
“And I’ll tell you some of what I heard coming from my opponent it was really hard not go, ‘whaaaaaat did you just say?!’” Clinton said.
As they spoke, the campaign’s massive, long-planned get-out-the-vote effort was kicking into gear across the country.
“It is tedious but we do it with great love,” said one campaign worker.
Clinton aides say nearly 1 million people have signed up to volunteer over the next four days.
“Hi, my name Barth I’m calling from the Hillary Clinton campaign,” says one caller as he cold-calls.
The operation is run by veterans of the vaunted Obama turnout effort in 2008 and 2012.
Using public data, the campaign has already rated every potential voter on two sliding scales of 1 to 100 - one scale for the likelihood they will vote, another for their level of support.
High support, low-propensity voters get the most visits.
“You would be doing yourself and your family and the country, Florida, all of the above a huge service if you get out to vote early for her,” one campaign worker says as she goes door-to-door.
In the south, Congressman and civil rights icon John Lewis has been leading hundreds of early voters on what he calls a “march to the polls.”
Clinton aides insist their ground game advantage is enough to repel a late Trump surge in some battleground states and even Democratic states like Michigan, where Clinton was today after polls showed Trump getting a little too close for comfort here.
Meanwhile, at a Clinton rally in North Carolina, the crowd shouted down a heckler who supported Trump, and he refused to take orders from the commander-in-chief.
“Hold up -- I told you to be focused and you’re not focused right now,” he said. “Everybody sit down and be quiet. You’ve got an older gentleman who is supporting his candidate. He’s not doing nothing. You don’t have to worry about him. This is about folks not being focused.”
“First of all -- hold up -- hold up -- we live in a country that respects free speech,” Obama continued. “Second of all, it looks like maybe he might have served in our military and we gotta respect that. Third of all, he was elderly and we gotta respect our elders. And fourth of all, don’t boo. Vote.”
CBS News’ Major Garrett gave his undivided attention to Donald Trump today.
“We’re asking for the votes of Republicans and Democrats and Independents and first time voters of which there are plenty,” Trump said on Friday.
That in a nutshell is Donald Trump’s get-out-the-vote machine -- exhortations from the podium with almost no follow-up.

At Trump rallies, merchandise sales are brisk, but volunteers with voting information are often overlooked.
Trump advisers say they can live off RNC field work because their supporters -- many brand new to politics -- are self-starters who need no hand-holding.
“They go from being a non-political person to wearing Trump shirts and buttons. It’s a beautiful thing,” Trump said.
The Trump campaign has built an elaborate system to monitor supporters via Facebook, Twitter and Instagram. Social media activity is used to track early votes and likely Election Day activity. Reminders are sent online, not through traditional means like phone calls or door knocks.
Can it work? Trump is betting everything that it can.
Ryan MacKenzie, a state representative in equally divided Lehigh Valley of Pennsylvania said trump motivation is through the roof and might be enough to deliver the first GOP victory in the Keystone State since 1988.
“That is something you can’t quantify it is not in the data is not in the metrics, it is not in the number of offices that any campaign is going,” MacKenzie said.
That state representative said he’s seeing something this election no one’s ever seen before. He says when the trump campaign and state party ran out of yard signs supporters here went to local printers then designed and paid for their own.
