Epic Media Bias

I've been trying oh so long to let you know
Let you know how I feel
--Phil Collins

Although 'never before' statements carry the risk of recency bias, President Trump's claim may be correct, at least with respect to the mainstream media.

Never in the history of our Country has the “press” been more dishonest than it is today. Stories that should be good, are bad. Stories that should be bad, are horrible. Many stories, like with the REAL story on Russia, Clinton & the DNC, seldom get reported. Too bad!

Seems ripe for academic research. It would be interesting, for example, if Groseclose's (2011) methodology were applied to panel data.

Suspect that a beta coefficent estimating the relationship between media bias and time would be positive and significant, which would position recent slant at top of trend.
