Knowing that Senate Republicans will exonerate, She is giving more of them time to come out and openly admit that they won't convict regardless of any evidence presented. The clearer it is that Republicans are corrupt, the better.
Given the fact that there's national ambivalence over impeachment, this lowers impeachment's profile until such time that it's worth taking up again..i.e. something changes the calculus to make it more likely that the Senate GOP would have to take a trial more seriously. OTOH, Pelosi has probably gone a long way toward satisfying the more outspoken members of her party in the House - she gave them their impeachment. And now it's as clear as day that Mitch McConnell has no intentions of taking it seriously at this time, which is something we've known for a while - certainly something Pelosi has known for a while. Impeachment's profile gets lowered and they can focus on other issues more important to voters and look less like they're going on offense.
Please. Failure to deliver the writ to the Senate in rather short order just bolsters the argument that It's a weak case Dems are afraid to advance, that it's all political, that it's not because Dems feel an urgent moral obligation to cleanse the office of the criminal now occupying it.
