"Vivi" pulled a very ill-concieved gambit of trying to get MAGA to vote for him to 'save trump' which is both wierd and unnecessary- at best.

In short: he totally DeSantis'd it

Vivek has still been riding Trump's dick.

Vivek hasn't even criticized Trump on the many mistakes that Trump made.

Don't see why Trump would feel the need to attack him now unless he had internal polling data showing Vivek was cutting into Trump's support base.

It is not a sign of strength to attack Vivek right before the first primary caucus.
