Dan Mitchinson: US correspondent on Donald Trump and Joe Biden dominating in Super Tuesday - Heather du Plessis-Allan Drive

Former president Donald Trump has dominated Super Tuesday in the US, as voters pick their preferred presidential candidate.

Reports are projecting he's won the Republican Primary in Virginia, North Carolina, Tennessee, Oklahoma, Maine, Arkansas, Alabama and Texas - beating rival Nikki Haley in each.

US correspondent Dan Mitchinson says support is still running high among Trump's base- there's nothing that could deter prospective voters.
