What's happened since the last debate
It’s been nearly six weeks since the candidates vying for the Republican nomination last met on the debate stage.
A lot has happened since then.
Former Vice President Mike Pence suspended his campaign, prompting audible gasps when he made the announcement on stage last month at the Republican Jewish Coalition's Annual Leadership Summit in Las Vegas. He was the first major candidate to drop out of the race.
Two other hopefuls failed to reach the Miami debate stage: North Dakota Gov. Doug Burgum and former Arkansas Gov. Asa Hutchinson. That means Wednesday’s debate will be the smallest of the three, with just five candidates in the spotlight.
What to know about the 3rd Republican presidential primary debate
One thing hasn’t changed, though, and that’s Trump’s commanding lead over the GOP field.
While the former president is once again snubbing his opponents, he won’t be too far away as he holds his own rally in Hialeah, Florida.
