Donald Trump leads Marco Rubio by a 2-1 margin -- 46-22 percent -- in Quinnipiac University's final poll ahead of Tuesday's Florida primary. They're followed by Ted Cruz with 14 percent and John Kasich with 10 percent.
The results are almost identical to Quinnipiac's survey last week, which had Trump ahead 45-22 percent.
"At least when it comes to this presidential primary, Florida might change its nickname from Sunshine State to Landslide State," Peter A. Brown, the poll's assistant director, said in a statement Monday. "Sen. Marco Rubio, who has staked his future on wining his home state, looks like he'll soon be toast. He trails GOP leader Donald Trump by more than 20 points with polling through Sunday night.
"There are very few examples of candidates making up that much ground in 24 hours."
The gap between Trump and Rubio has varied widely in recent surveys, though all show Rubio trailing -- in some cases by as little as 5 or 6 percentage points, and in others by more than 20 points, depending on the date and methodology. Quinnipiac polled 615 self-identified likely GOP voters Sunday; its survey has an error margin of 4 percentage points.
On the Democratic side in Florida, Hillary Clinton is way ahead of Bernie Sanders, by 60-34 percent with an error margin of 4.3 points.
