The second round of two Democratic Party presidential debates has taken place in Florida, with more than 20 candidates vying to take on Donald Trump in next year's election.

The front-runner, Joe Biden, came under fierce attack from Kamala Harris for his record on race. Eric Swalwell challenged the older candidates to hand the torch over to a new generation. And the lesser known Marianne Williamson said she would take on President Trump with a campaign of "love".

So, at this early stage, which of the debate strategies paid off and who might be disappointed with their performance?

Todd Graham - the five times national debate winning coach at Southern Illinois University - gives his take on the candidates skills.
