There’s a ‘race’ going on.
Two Races Pelosi and Schiff Are Racing Court Rulings For Impeachment Vote, and IG Report for Narrative:
In the summer people lose interest in politics and will be uninterested for the two and a half months leading up to the Republican Convention. That is why the DIMS are crying it is so unfair they hold their convention in July. Nobody will really be paying attention.
After 24 August it will be election 24/7 until November. Legislative work will grind to a halt
The DIMS have 5 Months to accomplish something and distance themselves from the Clown Show, hoping voters have short memories. But if impeachment goes into March or April, the clown show is all anyone will remember about this Congress.
Even expediting a cases before the Supreme Court it could be March or April before they get a judgment.
They may have a more nefarious reason. I think they need to prevent Trump from replacing RBG in 2020 claiming a President under the cloud of impeachment cannot nominate a Justice to replace her.
