At PolitiFact, this is our fifth presidential cycle. We’ve published more than 23,000 fact-checks since launching in 2007, all using our Truth-O-Meter, which rates claims on a scale from True to Pants on Fire false for the most ridiculous claims.
If PolitiFact is new to you, there are a couple of rules of the road. First, we don’t fact-check every claim every candidate says. We couldn’t … we’d be dead. But seriously, we focus on claims that are particularly interesting, or in the news, or obviously potentially wrong.
Our grading scale tries to measure both the literal truth and how voters might interpret a politicians’ words. So if Haley claims that DeSantis is against fracking, it can be more complicated to fact-check than you think. DeSantis, while running for governor in 2018, did promise to ban fracking and prevent oil drilling off Florida's coast.
But DeSantis said that what applies in Florida doesn’t necessarily need to apply everywhere. "And so when we're doing that, that is not saying that I think that should apply to Louisiana or Texas and all that. So, that will continue. And we want them to be able to do it, and we also want them to be able to use hydraulic fracturing," DeSantis has said.
We've fact-checked the candidates on stage in Miami 41 times this year. We’ve fact-checked DeSantis 16 times, Haley and Ramaswamy each eight times, Scott six times and Christie three times.
We'll be drawing on those previous fact-checks, as well as the thousands of other claims we've vetted, throughout the night.
