US election 2020: 'I voted for a guy named Trump' - President casts his ballot in Florida

Donald Trump has cast his ballot in the US presidential election, telling reporters: "I voted for a guy named Trump."

After voting in West Palm Beach, Florida, the president also took the opportunity to attack mail-in ballots - warning that they can never be as secure as voting in person.

Describing his experience at the polling station as "perfect and very strict", he added: "It was a very secure vote - much more secure than when you send in a ballot, I can tell you that."

The president said that that he will be holding "three big rallies" today, and claimed: "I hear we're doing very well in Florida and every place else."

To secure the White House, winning in Florida is essential.

The state has consistently voted for the victor in every election except one since 1964 - and no Republican has won without the state in almost a century.

With 29 electoral college votes up for grabs, it's the largest swing state and crucial for gathering the 270 votes needed.

Most polls show Mr Biden narrowly ahead in Florida. History suggests that, if Mr Trump loses here, he'll likely lose the White House.

The election will take place on Tuesday 3 November - just under two weeks away.

Analysis: Donald Trump knows Florida voters are key

On the road to the White House, Florida is a must-win prize.

It has consistently voted for the victor in every election except one since 1964, and no Republican has won without the state in almost a century.

With 29 electoral college votes up for grabs, it's the largest swing state and crucial for gathering the 270 votes needed.

Republicans and Democrats see the large pensioner population as a key voting block, and both campaigns have made frequent appearances here in the run up to 3 November.

History shows the key to victory in the state lies with winning the I-4 corridor - a stretch of seven counties from Daytona Beach to St Petersburg. Since the 1960s, whoever takes those has secured overall victory.

Traditionally a much tighter race than in other areas, most statewide elections have been decided by less than a percentage point.

But the good news for election watchers is that Florida's results usually come out early and are seen as a clear sign of which way the national election will fall.

Donald Trump knows he has to carry Florida to get a second term.
