And it's likely to be a tense competition.

Here's what you need to know about the race for the Liberian presidency.

In October's first round of voting neither incumbent President George Weah, nor his main rival, former vice president Joseph Boakai, managed to secure over 50% of the vote to claim an outright victory.

In fact, there was only a razor-thin margin dividing the two.

Weah got 43.83%, Boakai 43.44%.

What that's set up is a rematch of the second round in the 2017 election.

That time around Weah, surfing on a wave of popular support, defeated Boakai with over 61% of the vote.

He won on a promise to tackle corruption and improve livelihoods.

Six years later and some voters are disenchanted.

That's particularly over Weah's perceived failures to tackle corruption, high youth unemployment, food inflation and general economic hardship.

He's blamed the global health crisis and consequences of the war in Ukraine for not delivering on economic targets.

For the second round, 18 candidates have now been excluded from the race.

Maja Bovcon, senior Africa analyst at risk intelligence company Verisk Maplecroft, says victory will go to whoever manages to garner the support of the largest number of those eliminated candidates.

So, does that give someone the edge?

Weah has secured the endorsement of the CCP that came fifth in the first round.

However its candidate, Alexander Cummings, has remained neutral.

Boakai on the other hand has secured the endorsement of three out of the four best performing candidates that went out in round one.

However, Bovcon pointed out that those endorsements still fall short of the 50% threshold required for victory.

For both presidential aspirants, a big unknown swing factor is the nearly 6% of votes that were invalidated in the first round.

Bovcon warned that as both candidates scramble to secure votes they are more likely to stoke division or dispute the results.

Though the first round was largely peaceful, she says the second could be tense and may result in unrest on the streets.
