Cruz isn’t even trying to be an alternative to Trump anymore. Cruz used to say he’d eventually win Trump’s supporters over. Then Cruz made the decision to lie about Trump in a particularly nasty and vicious way. It’s the equivalent of saying he can get by without Trump’s supporters in this race. That’s a losing strategy.
If the Cruz/ Rubio/ Kasich/ Bush/ Carson supporters would all get behind one of them, we can stop the fraud Trump. Even narrowing it down to two non-Trumps would help. But if we keep dividing the vote, Trump could sneak through.
