The [D] in that post is referring to domestic, not Democrats. Q Post 4871 clearly gives reference to [Domestic] in relation to the upcoming election.

Q never rarely gives dates on anything and when they do the months are written out (see Q4842, 4835, 4817 as examples).

Q Post 4889 in which the following was linked gave a good indication of where this was going:

This specifically deals with foreign involvement with US government representatives, which ties in well with Section 11 of the US_MIL LoW Manual.

Lastly, Q posts 4821 and 4822 make it pretty clear what is coming. In both those posts, it is talking about foreign powers controlling the White House which, by definition of the LoW Manual, makes it a belligerent government.
