I see no reason to believe that the conservatives want him to drop out, and many reasons to believe they want him to stay in.
They sure as fuck have a funny way of showing it
I am referring to the New York Times and CBS News and whatever other crap here, as conservative media. Not the modern meaning of conservative, i.e. Nazi, like Fox News or Newsmax. I'm not sure what they are saying about Biden needing to drop out but I am assuming they are also talking about it, with much of the same self-fulfilling prophecy aspect about it.
I would think that pretty much the last thing in the world they'd want would be for the Democrats to make an 11th hour switch to an entirely different candidate, and quite possibly a candidate who will inspire the sort of enthusiasm Biden's candidacy is sorely lacking.
My god dude
The enthusiasm you are perceiving or not perceiving is purely media created. You are consuming some made up bullshit and imagining that it corresponds to reality, and that the media will suddenly be excited about this new candidate. They will not. They will find problems with the new candidate just as genuine as Biden's fuckup of a debate, and if you start wringing your hands at that point about what a big deal it is and how maybe now we need a new candidate that people can get some enthusiasm about, the people that bankroll the media that gave you that idea will laugh and laugh, with pure contempt for you, and with a certain quiet conviction of the sureness of their victory.
So.. nobody in particular in mind?
