Jeb can’t win. But he is using his superpac firepower to destroy everyone that stands between him and Trump. He is even running ads against Kasich in NH. Cruz will be next in SC.

Which is a good thing, particularly since you point out Jeb can’t win anyway. So Jeb is taking the Trump/Cruz opposition off the table for free. Looks like Jebbie tip-toes will get to still play on the main stage for a while longer. Unfortunately for Jeb, like Hillary, the more people who actually see them, the more they don’t like them.
