Talking Points Memo - Sen. Ted Cruz (R-TX) has the poorest understanding of climate science of all the 2016 presidential candidates, according to a report card prepared for the Associated Press by eight climate and biological scientists. On a scale from zero to 100, the scientists gave Cruz a six.
"This individual understands less about science (and climate change) than the average kindergartner," Michael Mann, a meteorology professor at Pennsylvania State University, wrote about Cruz's comments, according to the AP. "That sort of ignorance would be dangerous in a doorman, let alone a president."
The leading GOP candidates all ranked below 25 while the Democrats all ranked above 85.
