Super Tuesday is drawing to a close and what a day (night) it has been.
Thanks for following the blog and be sure to keep checking in on theage.com.au and smh.com.au for news and analysis.
So, what happened? In short, the Democratic presidential nomination is now a two-man race between Joe Biden and Bernie Sanders. Biden has enjoyed a stunning comeback after looking finished only a matter of days ago, while the high-profile campaigns of Elizabeth Warren and Mike Bloomberg appear all but over.
Biden looks to have picked up the most delegates in at least nine of the 15 states or territories that went to the polls on Super Tuesday - including in the electorally-powerful state of Texas.
But Sanders was on track to pick up a big win in California, the state with the largest number of delegates.
