Pardon me for mentioning what may already be looming in everyone's minds, but I haven't seen it discussed yet and thought I would throw a seed crystal into the supercooled medium of this page.
I am not a Q fanatic, so I take no arrows for being imprecise in my reference, but I seem to recall that Q placed a specific emphasis on how the "First Arrest" would have galvanizing significance.
In light of recent events, I would float the speculation that the First Arrest will be of President Trump.
It has some interesting explanatory power. First of all, if Trump is in a state of "devolved" authority, being arrested by an occupying foreign power is probably a "red line" that would finally trigger military countermeasures. Secondly, it would fit exactly well with the entire document scenario (a tar-baby trap with the documents as bait) and Trump's seemingly strange ebullience over the whole subject, as though he is itching for the trap to spring. The "trap" in this case being his arrest and getting the Deep State to cross the Rubicon that his Presidential Executive Orders anticipated.
There may be more along the same theme, but I think fellow anons can grab this bone and chew on it. Please do so. I would love to see if I am on the right beam.
You have to consider that they "can indict a ham sandwich". They will probably indict him over something they found in the raid, whether or not they even have a case. In fact they may have already indicted him and it is sealed. If/when they unseal any indictments against Trump then they will make the arrest. I don't but them saying they have to wait until after the election either. They cheat every time, all the time. Why hold back a sure thing when they can interfere with the election and kill the morale of MAGA?
Remember - an arrest doesn't have to stick. They don't need a conviction (right now anyway). They just need to demoralize MAGA voters enough that they stay home. Then they keep CONgress.
As for the "they will fight" part from the Q post - that could mean the left will fight to publicize the arrest far and wide, and smear Trump with everything they have. They have to convince everyone Trump is guilty, suppress the conservative votes, and make sure the left still votes. That's a lot of fighting.
