JEB's SuperPAC is going to attack Rubio from the left on abortion and Iran, are they out of their minds?

In the New York Times there is a story of how JEB's cronies in one of his affiliated SuperPACs are going to buy ads attacking Rubio from the left:

Right to Rise held focus groups in New Hampshire shortly after the Oct. 28 Republican debate, in which, among other things, the participants were quizzed about Mr. Rubio’s missed votes on two Republican priorities: cutting federal funding for Planned Parenthood, which carries out abortions, and blocking President Obama’s nuclear agreement with Iran. The responses suggested that both could provide potent lines of attack.

In an attempt to blunt Mr. Rubio’s appeal and showcase a potential vulnerability against the Democratic nominee in the general election, Mr. Murphy recently showed some Republicans a video portraying Mr. Rubio as too extreme on abortion. A longtime opponent of abortion rights, Mr. Rubio said in a debate in August that he had “never advocated” laws that would allow abortions, even in cases of rape or incest.

Mr. Murphy has privately said to several people that Right to Rise would be ready to devote up to $20 million to fighting Mr. Rubio, according to several people told of the conversations. Asked about the figure, Mr. Murphy declined to comment.

They are going to spend $20m making the same arguments that Democrats are going to make against Rubio, is that really a way to win a Republican primary?  And does JEB want to be associated with an attack on Rubio's position on the Iran treaty?  Arguably the worst agreement this country has ever signed?

This won't help JEB, it will absolutely DOOM him.
