Not so sure about Cruz and Rubio being worth a shit in my opinion, but I LOVE Rowdy Gowdy. Cruz and Rubio are loser establishment types who pretend to be something they aren't. I would not mind if they left for good and were replaced with someone like Gowdy, Giuliani-type, Sheriff Clarke, Trump etc...
I like Cruz. He has fought hard and basically alone on issues.
Not sold on Rubio. He seems a bit status quo/weak to me at this point in his career. Maybe this election will give him a boost in the right direction before it is too late.
Remember Cruz was second behind Trump because he is also someone who both parties do not like. He makes too many waves. Good waves in my opinion.
