Cruz never went on TV and said, yeah, some of my stances are those of a Democrat. Trump did so in July.
What stances? I'm just curious, not doubting you. However, if it was merely a vague statement by Trump, that helps explain why he has the poll numbers. He is appealing to a broad cross section of the electorate, especially when espoused on television where most of the "ill-informed" form their opinions of the candidates.
BTW, not a Trump supporter nor anyone else at the moment.
