The headline you linked is a lie. Trump didn’t “float” Brown as VP. He was asked and said he would “consider” it, the same as he said about Cruz and pretty much anyone else he is asked about out of the blue.
In any case, “no” is the proper answer as to whether Scott Brown should be considered for VP. We would also accept “hell no”.
Instead Trump talked about handsome Brown is, as if that were a qualification.
