I tell you what - there is something to be said about the "left wing media" not posting much about it - don't you agree?
Umm... no. I can't say that I would agree. (Although to be fair I don't pay attention to "left wing media" so who knows or cares what they're saying.)
As far as the mainstream media goes, though, I don't really think there's much to be said there. First, Trump's had a ton more allegations and of course he's president now, so a google search right now is a very bad way to test this.
Also, allegations get mainstream media play when they are well-documented and well-supported or there are many of them. If this is not getting a lot of play, part of it could be because there just isn't enough evidence/corroboration yet. (That doesn't mean it isn't serious or it didn't happen, but mainstream media outlets for the most part don't play up stories like this unless they are pretty solid, at least compared to .)
And finally, I don't remember much mainstream media coverage of Trump's assault allegations during the 2016 primary. The "grab them by the pussy" audio got a lot of play, but that was also during the general election campaign and the actual assault allegations weren't mentioned much. (Especially compared to, say, her emails.)
So is there some left-wing hypocrisy here? Probably. There almost always is. Is there a mainstream media bias? I don't see any evidence of that.
And honestly... what's the relevance to the election? If someone is trying to decide between Trump and Biden, are they really going to choose Trump because of a sexual assault allegation against Biden? Really? Who would do that?
