This election has already proved remarkable for the record number of postal votes on early voting going on in many states.

While the Democratic candidate, Joe Biden, is currently leading President Trump in the national polls, that doesn't guarantee victory.

The race is very much still on a czar, North America editor John SoCal explains from one of the states being watched very closely.

Georgia One week to go.

And Joe Biden has Georgia of all places on his mind.

No Democrat has won here in decades.

Yet polls suggest this once rock solid Republican state is there for the taking.

Theo famous Southern hospitality was markedly absent from the hundreds of Trump supporters who lined the roads leading to where he was speaking on.

Look at the difference between this on the Trump rally.

Social distancing strictly maintained.

Don't move out of your white circle masks, not an option.

I run to unite this nation and to heal this nation.

I've said that from the beginning is badly necessary.

So where are we with the 2020 race?

between Donald Trump and Joe Biden In terms of national polls, Joe Biden's been enjoying a significant lead across the country.

Latest averages suggest that he's as much as 10 points up over Donald Trump.

But in U.

S elections, national polls are slightly meaningless.

Remember, in 2016 Hillary Clinton won the popular vote by three million and still lost the presidency to Donald Trump.

The key to this election is what happens in the swing states.

Joe Biden has a steady lead in Wisconsin, Michigan and Pennsylvania, the three northern industrial states that propelled Donald Trump to victory in 2016.

But he's also level or ahead in Iowa, Georgia, North Carolina and Arizona.

And it's the same picture in Florida and Texas on where Joe Biden toe win one of those last two states.

It's hard to see how Donald Trump could win.

The remarkable phenomenon about this election is early voting in 2016 135 million Americans cast the ballot in the presidential election with a week to go.

So far, more than 60 million Americans have already voted, and that means if turnout remains the same well, nearly half of Americans have already voted.

What's also astonishing is the number of young people who voted early in 2016.

In Michigan, 7000 people aged between 18 and 29 went to the polls before polling day.

This time round, it's over 140,000 so far.

In other words, a 20 fold increase.

Andi.

It's a similar story in Florida, on North Carolina and in Georgia.

That number is 31,000 in 2016.

It's already 170,000 this year.

Thes air numbers thought to favor the Democrats massively.

But Donald Trump says he's confident the next Tuesday there'll be a red wave of his supporters coming to vote that will propel him to victory.

He's doing multiple rallies per day today.

He's on route to Michigan, Wisconsin, on Nebraska.

Now I've got to say, I'm working my ass off here on.

There's a sophisticated data mining operation that takes place at these events, ensuring that everyone who attends is also registered to vote.

This was his successful 2016 playbook.

I just want to update you on the early voting here in Georgia.

Two thirds of the total turnout from 2016 have voted in Texas.

It's 82% that is giving Democrats cause for optimism.

But this time four years ago, with a week before polling, Democrats were similarly optimistic.

We know what happened a week later.
