I wouldn’t go so far as to say they’ve teamed up.......Cruz gave away that opportunity at Convention. The only one now who can make it even appear they’ve ‘teamed up” is for Trump and Cruz to appear together.....I question if that will happen.
They teamed up as a coalition for free speech online, for good judges, etc.
That’s the best you can hope for sometimes, an uneasy truce.
I’m not even sure it would be helpful if they did stand together.
Cruz had trouble building a team against the internet giveaway despite having so much research and powerful witness testimony.
Other senators might bristle if Trump shows any signs of favoring Cruz.
