I have all the same complaints about Rubio but I’d definitely take Trump/Rubio over Cruz/whoever. That may be Trump’s only play with the GOP throwing all resources against him.
Rubio has shown his bad side but there were also glimpses of a different candidate. Cruz is all evil.
I’m not a Rubio person, but it is true that at the end, Trump stated, “He’s got a good future.” There WAS an olive branch extended of sorts.
