Point by point:

The Republican party views Ramaswamy as a standout figure.
Since Desantis imploded eyes are elsewhere. Ramaswamy stands out because he is well-spoken.
Might make a good running mate for Trump time will tell.

The main question is whether individuals like Marc or Pat would vote for Ramaswamy.
No it would be a wasted vote. I was going to vote for Desantis but he needs to learn how to run a campaign first.

Ramaswamy is expected to make a significant impact in the upcoming Republican debate.
No doubt but he won't get within 30 points of Trump.

Trump plans to overshadow the debate's outcome by turning himself into authorities in Georgia, aiming to dominate the news cycle.
Smart play.

Trump's intention is to detract attention from the debate's winners and focus it on himself.
Smart play

Most Republican candidates, except for Christie, continue to support Trump despite his tactics.
Christie will be weeded out soon. A true non-factor
