Wait, was she found dead after her video went viral or before?

In a healthy democracy, religious preference does not trump legal inquiry in suspect deaths - eg autopsy.

In a healthy democracy, someone with a daughter making claims of long-term sexual abuse by her mother and family, and a son that was convicted of kidnapping and torturing a Palestinian boy (leaving him naked and beaten in a field) has no possibility of a continued political career. If there are no better alternative politicians from your political party to fill your role, then that is an indictment of your entire party.

But she is a proud ultrareligious racist fanatic and so is her party, and so all of this is no problem for them. Nor apparently a large amount of the voters - her party has 7 seats in the current Knesset. Which is more seats that Israel's only firmly left-wing party 'Hadash–Ta'al', which holds 5.

More info here, but I can't speak to the veracity of this source.

Strook is a mother of eleven and a grandmother of twelve. In 2007, a Palestinian boy was found severely beaten and bleeding after escaping an alleged torture session.

It was later revealed that Zviki Strook and his friends had entered a Palestinian neighbourhood, captured a 15-year-old boy, handcuffed and beat him, stripped him, and allegedly hit him with an ATV (all-terrain vehicle) before leaving him tied up in a field. The victim escaped hours later, suffering from severe injuries.
