During the whole Trump tenure, I have seen a bunch of what I would call discrete to very obvious Q hints and references. The most obvious has gotta be a rally speech where he kept talking about the local farmers growing cucumbers. The first time he said it was like 'cu-cumber'.. and then 'cuuuuuuuu-cumber' and then... 'we really love our cuuuuuuuuuuuuuuuuu-cumbers.' Anyway.. that was directly from him and that one stuck with me.
What other ones would you consider obvious?
A good one from Dan Scavino:
On June 17, 2020, Q shared a "Silent Majority" meme to which they added a watermark in the bottom righthand corner: https://qanon.pub/#4475
Dan Scavino shared Q's watermarked version of the meme 5 days later on June 22, 2020: https://twitter.com/DanScavino/status/1274917474115485698
Also, here's the original meme without the watermark. It was shared by Mailk Obama the day before Q's drop: https://twitter.com/ObamaMalik/status/1272963575292796928
