IMO ...Trump has two requirements for a VP:
One ...Absolute slavish subservience. Especially after Pence’s “betrayal,” he will insist on a VP who always will put Trump’s interests ahead of his/her own. This will keep Haley, Cruz, Hawley, Rubio and any other politicians with future Presidential ambition off the ticket. Likewise, he’ll never choose Graham because while such a blatant lickspittle has his uses, he doesn’t project the strength and sophistication that Trump associates with his brand. DeSantis was never going to be his running mate because they’re both Florida residents.
Two ... Complementing his brand. He will insist on someone who “looks the part.” While he may choose a woman, it will most likely not be Stefanik or Huckabee-Sanders because – in his twisted, misogynist mind – they don’t look like the kind of women who should be standing at his side.
It's possible he'll pick Kari Lake, with him wishing the whole time that she were just ten years younger, had longer hair and bigger tits. Lake claims she was the victim of massive voter fraud just like Trump. And unlike those other pussies Trump endorsed in the midterms, Lake refused to concede. Donald will like how “Trump - Lake” sounds. Like someone named a huge body of water after him. He’s just that fucking stupidly narcissistic. Trump is transactional - what can a new VP candidate GIVE him? Compared to what he already has in hand? Very little. If outright bribes were allowed or available, it would be an open field. Lake is totally in the bag for him, is as batshit crazy as he is on election bullshit, might help him win Arizona and win over suburban women (or so he’ll think).
It's possible he might pick Ramaswamy. He fits his brand - A slimy grifter. And he ass kisses Trump with the best of them. Trump most likely loved when he publicly announced he would voluntarily withdraw from the Colorado primary after Trump’s name was removed. That’s the kind of ass kissing Trump expects. Even though Ramaswamy is brown and not Christian, Trump has demonstrated he can tell the MAGAs anything and they will agree with him. In fact after Pence “betrayed” him, Trump will probably see Ramaswamy not being a Christian as a plus. He will have no Christian faith to feel guilty about when Donald wants him to break the law. And Ramaswamy’s race and religion will mean Trump most likely won’t find him as threatening. But he is a big personality and Trump might not like that. He's a long shot.
Other long shots would be JD Vance, Tucker Carlson and Micheal Flynn. Flynn has zero future except as a limpet on Trumpdom, and both he and Trump know this.
Trump’s ideal pick would be no one. He doesn’t want to share and he doesn’t want to admit he is mortal and susceptible to illness and death. And he hates the existence of the office of VP, because he can’t fire the VP. So it's possible he’s going to go the mob boss route and try to pick his son Don Jr. That’s as close to nothing as he can get. Well, Eric would be even closer to nothing, but I don’t think he’ll go that far. Plus, it's the easiest way to insure his legacy. Then that family member runs for president to continue the Trump dynasty.
Regardless of who Trump ultimately chooses, the one thing we can all look forward to is the vicious public backbiting as the candidates try to impress Trump by mercilessly ass lick and back-stab each other. That’s what Trump lives for - he’ll just sit back with that dough-face while they try to out-batshit and out-sycophant one another. He’s gonna love that - which is why he hasn’t said who he will pick, because just teasing it out there will get them all in order to start the butt-snorkeling.
