I don't mean to be rude, but this sounds fairly anti-semitic. "It doesn't matter about what all the Christian groups think, what matters is that the Zionists [implied to be Jews?] are buying the legislation".

This might definitely not be your intent - but that is for sure how I am currently parsing your comment.

Agreed.

1. Obviously anti-semitic

2. Not even true. The Christian Right lobby is HUGE and includes evangelical Protestants, Catholics, and LDS.

3. The Christian far right is significant and spent over 10% of the total lobbying spend in the last election cycle.

Christian Zionists are a very import part of the Israel lobby and extend the power of that lobby in many places that it otherwise wouldn't be. Given how many left leaning Jewish people in the US have decreased their support for Israel, Christian Zionists give them a real ground support to the movement that is otherwise more dominated educated elites.

And depending on your definition of 'Zeal' the christian zionists often have more. A educated Neo-Conservative might be a strong Zionist but not will not come across as having Zeal, while a Baptist Christian Zionists might come of as pure Zeal.
