At this point, I'm confident that we don't really need any other drops in order to win the Presidency and the Senate. Trump has been more than adequately damaged, and the disparity in on-the-ground operations will see to it that the job is done as far as both goals are concerned.
The timing of drops is more of a fun spitball topic..
(But if there is any sort of magic information out there that suddenly makes the bowels of the earth open up such that seats like Rubio and McCain are immediately vulnerable.. I WANT IT.)
