Three Democratic incumbents running for re-election in states President Trump won are among the least-popular senators, according to new polling data.

Morning Consult surveyed more than 275,000 registered voters from the beginning of January through the end of March, asking them to indicate whether they approve or disapprove of their senators. On the list of the ten least-popular senators, Republicans take the top three slots with Mitch McConnell, R-Ky., Jeff Flake, R-Ariz., and John McCain, R-Ariz. But slots four through six go to Trump Country Democrats, all of whom are up for re-election in November: Claire McCaskill of Missouri, Joe Manchin of West Virginia, and Tammy Baldwin of Wisconsin.
