I still think Cruz stock, for purposes of getting the nomination, is currently undervalued. That article just reinforces that belief. All of the GOP front runners are circus freaks. Cruz, as disgusting as I find him, is the only one of substance out of Carson, Trump, Rubio and Cruz.
I know that Rubio is theoretically a strong candidate, but I just don't think there is any way he can hold up - if he can ever become a true front runner. The establishment really prefers Bush, but I think it acknowledges that Bush cannot win, and on paper, Rubio is "the guy". I just don't think the establishment thinks he passes the eye test, and I don't think they will firmly rally behind him.
If the establishment wants to play the long game like Cruz always does, they should let one of the crazies get the nomination, and get crushed in the general, and then try to go out and reform the Republican Party, casting aside the crazies, and figuring out how to get independents and moderate democrats to come back to their party. Hope the economy sputters in Hillary's first term, come with a message of "the crazies are gone", and try to win in 2020 and beyond.
That, or just say "fuck it" with respect to the Presidency, and focus on Congress and state legislatures.
