Why hasn't Q been posting?

I think Q doesn't want the enemy to get any ammunition prior to the election. Remember when all the media outlets wrote about the Q phenomenon? Q specifically mentioned that the timing to allow Q into the collective consciousness was planned. The secret service let all the Trump supporters into the rally with Q shirts / signs, etc. in order to prompt the deep state to write the articles well in advance of the election.

This was planned so the enemy blew their load far in advance of the election.

If I had to guess, I'd say Q will be back right after the midterms.

It will be interesting to see whether the deep state blames the recent spate of bomb threats on Q supporters. But now if they do, it won't be easy since Q hasn't been posting and hasn't been in the news.
