Lemme repeat since you have a problem understanding.
1. If Trump is running in primary, NO ONE has a chance of winning the primaries.
2. All the contest there is for the VP / Trumps running mate position. And that has absolutely NO, ZERO relation to who is at what position in primaries below Trump.
3. Barring death or disability, it is extremely unlikely to stop Trump from running in presidential election, he can run EVEN from the jail.
The reason I said Vivek has somewhat lesser chances for becoming Trump's running mate is because he has irked Trump's ego. The only thing he should not have done.
That being said, Trump is more vindictive towards Republican party itself.
This dude is a grifter literally the only people stanning him on the internet I see are the PHUUL SAAPOORT SAAAR mofos and the NRI greencard fobs.
Trump was never going to pick him as VP, he is dead weight. And now with the "disrespect" Trump definitely not picking him. What constituency would Trump even need him for, he is useless. The only way he would have been useful to Trump would have been if he tried acting like a Trump proxy at the debates and attacked Trump's opponents while building up Trump as some sort of loyal foot soldier, like what Putin does, he get Yes men who support him to run in presidential elections while basically just supporting Putin and boosting him. Then he could have pulled off a cabinet position like Pete Buttigieg. Instead this guy tried going after the Don himself and now he is finished. All the Trump people who were lukewarm from the very beginning towards him, b/c he was praising Trump to get on his good side, now completely hate him. See for yourself in the comments.
