This year is the third time that Joe Biden has run for the presidency. If the signals on Betfair for tonight’s South Carolina Primary are correct, he is about to finally win a race.

Biden expected to land big win in SC

The fourth primary towards the Democratic Nomination has been an extraordinary betting heat already. Biden was matched down to [1.15] early but ceded favouritism following heavy defeats in Iowa and New Hampshire. Yet after a transformative week, he’s back down to [1.1] – equivalent to a 90% chance.

The polls certainly point that way. The RealClearPolitics average lead is 12.5%, with five of the last nine showing Biden 15% or more ahead. I reckon the bigger margins are right, factoring in the momentum of recent days. Fivethirtyeight give him a 95% chance of victory.

#SouthCarolina @FiveThirtyEight Model:

Share of vote:
Biden 40%
Sanders 21%
Steyer 13%
Buttigieg 9%
Warren 8%
Klobuchar 5%
Gabbard 3%

Chances of winning:
Biden 95%
Sanders 4%

Evidently, the former VP was boosted by his midweek debate performance. As explained beforehand, I backed him at [15.5] for the nomination in expectation of this endorsement from James Clyburn.

I know Joe Biden.

I know his character, his heart, and his record.

Joe Biden has stood for the hard-working people of South Carolina.

We know Joe. But more importantly, he knows us.

In South Carolina, we choose presidents.

I’m calling on you to stand with @JoeBiden.

Tactical voting now liable to help Biden

Tuesday’s debate seems to have had a profound effect on the race which, within a few days, may become a dual. Every primary so far has involved tactical voting among moderates – for example Buttigieg was best-placed to thrive in IA and NH.

Now, however, neither Mayor Pete or Klobuchar seem viable. They will both be thrashed on Super Tuesday by Sanders and, at least in the Southern states with large black electorates, by Biden too. They will soon run out of money soon and endorse Biden.

Critically, Michael Bloomberg may have peaked. His second debate was better than his first, but still pretty grim. He isn’t a natural Democrat and it shows.

Bloomberg is in quite a lot of trouble. His national polls have stalled out or begun to reverse themselves. He's fallen to 11% in our CA polling average. In other Super Tuesday states, we aren't seeing the leads we saw pre-NV debate; it's a lot of stuff in the teens and low 20s.

Reportedly, Bloomberg hasn’t committed to a massive ad-spend after Super Tuesday. Again, expect him to back Biden.
