monarchy or imamate?

This link describes the monarchy Yemen had from 1926 till 1962. Do Zaidis today want a return to a Hashemite monarchy like in Jordan and Morocco, where leadership is passed from father to son, or an Islamic Imamate, where leaders are selected based on religious knowledge? I am just curious, not trying to promote either alternative.

The next link shows a list of the Imams of Yemen from 898 to 1962. Interestingly, the Imamate was not always passed from father to son. It would be interesting to know what criteria was used to select the new imam when it was not passed to a son.

Here is a link about the Hashemite leader of Jordan, i.e. a descendant of Hassan bin Ali, and a promoter of peace. His wife Rania is an inspiration to all women. Their Hashemite parliamentary monarchy is an example of what Hashemite leaders can achieve. May Allah continue to bless their Hashemite Kingdom.

See page 24 about the leadership of King Muhammad VI.

I'm not saying that these leaders are Zaidi, my point it that these countries with Hashemite leaders are peaceful stable countries, which compare favourably with other Muslim countries controlled by non Hashemites.
