Despite a barrage of negative ads against him from Democrats and Republicans alike, U.S. Sen. Cory Gardner’s approval rating did not budge in the last three months of 2019, according to polling released Thursday by Morning Consult. The research firm and news outlet, which surveys senatorial and gubernatorial approval ratings each quarter, found 37% of Coloradans approved of Gardner in the fourth quarter of 2019 and 40% disapproved of the Yuma Republican, who faces re-election this November.
