Though I'm not sure it'll happen, there's a thought going around now that Pelosi won't send to the Senate right away, instead she'll sit on the articles and do more fact finding.
I'm torn on whether this is a good idea or not.
On the one hand we know the Senate as it stands won't do jack shyte really and they're not even going to pretend to care about the Constitution or their Oaths (or their Religion for that matter) since they're saying already it won't be a long trial and they plan to call no witnesses.
On the other hand, trying to get more facts to prove Trump did indeed do the two articles he is impeached on before going to the Senate might just be a good idea, if only to throw as much at them as possible and thus as much evidence to the US public, so when the Senate acquits, the public knows that the Senate is total bunk and they can all be voted out next election.
I don't see it happening though. Pelosi won't hold back despite knowing going to the Senate is futile. The only hope there is after the bullshyte trial is that the Dems then take what happens to the campaign trail and show the public the truth, that the Republicans don't give a shyte at all about the US, only themselves and if the party won't change, then they shouldn't be allowed back into office until they return to the party of the US again.
