For those who missed it today, Rubio is the first to come out with a 2024 Trumpian platform:

“I support American greatness. And I have no interest in returning to the ‘normal’ that left us dependent on China,” Sen. Marco Rubio tweeted today, suggesting that he would oppose confirmation of President-elect Joe Biden’s national security team https://t.co/rdxi00rXog

So after being humiliated repeatedly by Trump, Rubio now wants to fashion his own Presidential aspirations after said bully.
