Here is a quote from one of them:
"Although 12th is a respectable overall ranking, one would have thought that former President Obama’s favorable rating when he left office would have translated into a higher ranking in this presidential survey," Edna Greene Medford, a Howard University professor and member of C-SPAN's historical advisory board, told Politico.The agenda is pretty obvious.
Cspan used to be fairly neutral. Not any more; if they lean any farther to the left, they’ll find themselves in China.
