evidence: Former U.N. ambassador Nikki Haley and Florida Gov. Ron DeSantis sparred over fracking at the second Republican primary debate Wednesday, with each making some questionable — and in some cases false — claims about DeSantis’s record on the subject. [...] DeSantis’s actions on fracking have been more nuanced than Haley’s attack suggests. In his 2018 campaign for governor, he promised "to pass legislation that bans fracking in the state." [...] DeSantis has not followed through on his pledge to pass legislation that would ban fracking in Florida. While serving in the U.S. House in 2013, he voted for a bill that would force the federal Department of Interior to defer to each state’s rules on fracking.
