9) He doesn't believe in climate change, an issue many Democrats have lampooned him for, in part because he leads the Senate's Space, Science, and Competitiveness Committee which oversees NASA. During a recent appearance on "Late Night with Seth Meyers" Cruz said "Debates on this should follow science and should follow data. Many of the alarmists on global warming, they’ve got a problem because the science doesn’t back them up."

Cruz's campaign told McClatchy the claim was "another garbage story in a tabloid full of garbage." The National Enquirer, by the way, endorsed Trump last month.
