The South Carolina GOP polling landscape heading into Saturday night’s debate hadn’t changed much in several weeks. Donald Trump was the clear frontrunner. Ted Cruz, Marco Rubio and John Kasich were anywhere from second place to fourth. Jeb Bush was anywhere from third to fifth, while Ben Carson was at the back of the pack.
That picture is according to four polls released between February 10 and February 13 and included in the RealClearPolitics South Carolina average.
There’s still plenty of time for things to change, though. And it’s important to note that none of the recent South Carolina polls were taken after Saturday night’s debate.
It’s too early to tell what impact, if any, the debate will have on polling. But for what it’s worth, a plurality of respondents to a poll commissioned by CBS said that Rubio won the debate, with Trump second and John Kasich third.
Let’s take a look at the polling landscape heading into the February 20 South Carolina primary.

The Road Ahead: A Lot Can Change Before Primary Day
It will take another day or two to get data from polls conducted after the debate. A lot can change.
In New Hampshire, polls conducted in the aftermath of Marco Rubio’s strong third-place finish in Iowa showed the Florida senator gaining ground and moving into second place in New Hampshire. The conventional wisdom was that Rubio was the biggest winner in Iowa. His stock in the betting markets, for instance, skyrocketed, while Trump’s plummeted.
Eight days later, Rubio was perhaps the biggest loser in New Hampshire, having finished in fifth place, behind John Kasich, Ted Cruz and Jeb Bush.
Rubio’s stumble in New Hampshire is likely especially good news for Trump. In the days after Iowa, Rubio’s standing in the national polls improved substantially. The conventional wisdom was that he would be able to unite the GOP as the “mainstream” candidate best suited to take down Trump and Cruz. Several polls backed up that conventional wisdom.
A national poll from Public Policy Polling, for instance, showed Rubio pulling to within 4 percentage points of Trump nationally, and Rubio actually leading the field in everything from a two-man race against Trump or Cruz to a four-man race against Trump, Cruz and Bush.
Rubio has the real momentum nationally- up 8 points and his favorability has gone from 49/34 up to 64/21:
Our new national GOP poll- Trump 25, Cruz/Rubio 21, Carson 11, Bush/Kasich/Paul 5, Christie/Fiorina 3, Gilmore 1:
Things bode well for Rubio as the field grows smaller- leads Trump 52/40, Cruz 46/40 in head to heads:
Eight days after Iowa, though, that conventional wisdom has taken a major hit. Rather than dropping out of the race after New Hampshire, Kasich and Bush are moving on to South Carolina, depriving Rubio of an opportunity to pick up votes from Kasich and Bush supporters. Even with Chris Christie and Carly Fiorina out of the race, the so-called “establishment lane” is awfully crowded, potentially paving the way for another Trump rout.
Rubio, whose poor performance at last week’s debate in New Hampshire may have set him back substantially, will get a chance to regain his footing on Saturday, when the leading GOP candidates compete in a debate in Greenville, South Carolina.
