You're basically implying that only someone who shares your political views can report fairly about you. Pretty toxic view.

Also, if journalists are reluctant to be identified as Republican, perhaps the Republican party should do some soul searching about why this is so.

Not toxic at all, that is absolutely true in this day and age. The most neutral news I watch is pbs which leans left. I’m not going to find illegal immigrant crimes on CNN for the most part, but I’ll find them all over Fox. I won’t find Trump scandals and hate crimes against minorities on Fox much but I’ll find them super highlighted on CNN.

Assuming there’s no bias is naive.

It looks like you're claiming that Silicon Valley is wrong when they talk about implicit bias, or Dems are wrong when they state that judges nominated to the SCOTUS by Republicans can't execute the law faithfully. Or that a call for more women in the boardroom is unnecessary because that implies that people are biased.

Note that I'm not taking a position on those implications, but am saying according to your logic the above is sound.

Also according to your logic Dems should do soul searching because lumberjacks and truck drivers are mostly Republicans...

You presume the independents are in the center. There are plenty of libertarians and conservatives disgusted by Trump and staying away from the Republican party until they get their act together again.

This poll took place in 2013 when the Repubs were the party of Romney and McCain --two Repubs, who according to quite a few Dem operatives, exemplify what Republicanism should be all about, so that is not a reason.
