It matters not what Trumps sees or does not see as a threat. In this case what matters is the effectiveness of his base in getting out the vote.
You have many “first-time voters,” whose political life began in 2016 with Trump’s candidacy. If they are also Q followers, and become discouraged when they finally realize they have been played, and no “white hat” is coming to the rescue, they may feel so discouraged as to not show up at the polls.
If we lose the HOR, it will be a disaster for Trump’s agenda - and perhaps his presidency or chances for reelection in 2020.
If you are correct that his base is key in the next election, then what kind of base does he have if they will not let his own advice guide them? Trump knows about Q, you have a take on Q. If Trump were to wholeheartedly endorse Q, you would have egg on your face. If Trump sees Q as a problem he will deal with it. He is the only one his base will really listen to on this subject. I hope that if you are correct that your efforts reach as many people as possible. I imagine Trumps reach is much, much further.
