Yes, most of the MSM has always been to the left, but there used to be some daylight between the two. In the last 5 to 10 years, though, it's simply merged with the DNC. Right now much of the time, you can't even tell the MSM's "straight news" on Trump and politics from opinion pieces. Even before seeing the classified memo, the MSM were calling its release "political" and defending Dems. They automatically take the DNC position, and that includes when they pushed the DNC line on "Russia" and pushes for Trump's impeachment though Mueller investigation has uncovered nothing.
