I disagree. First of all, I don't think she's smart; just an average level person.
Second, and I don't have any evidence, but I suspect she's a deep state plant tasked with getting into the Trump administration. Trump has been victimized by this kind of tactic several times, and has been fooled. It's probably hard for Trump to know whom to trust. And even if he can trust a person initially, that person can be turned on him by pressure. At least Trump fires people when he recognizes it. 2020 was a classic coup to remove Trump and it worked. Be he perseveres. Pretty soon the only option is to kill him. One option is to trick him into choosing a VP that is actually a deep state person, and then Trump is taken care of. Maybe Tulsi is such a person? She was part of the military industrial complex and checks all the boxes of a good plant (woman, color, military vet, democrat "convert"). Perhaps something like the Reagan assassination. Did any one else find that assassination suspicious when Reagan was an outsider yet his VP was a life long military and deep state guy? I doubt random crazies are the true explanation of any assassination in history. Random crazies aren't skilled enough to get at such high level people.
